Since the only way you can possibly know that is by measuring it, hence you have the calibration file on your PC, can you please share the colour volume tracking results for any primary colour, say, green?
If you are correct, your deltaE for Y should be reasonable.
For reference, here is BC Off. This is Rec709 mind you... Note the two red circles, Y Target and Y measured. They are close enough to consider reasonable that there is no issue.

Not like this:
BC ON, which from a standpoint of how the technology works based on what I read about it and even what you yourself have agreed, its my understanding its NOT possible to have the green with BC On reach the target Y which as you know is a target in relation to the measured white.
If you have found a way around that, then that's great! But you should be easily able to show us so we can see the measurements.

Also, note how much better tracking is overall with BC off, but also note that to the untrained (Not saying you at all) the tracking on BOTH appears to be somewhat reasonable (excluding Magenta) if one was looking only at the CIE chart, however the colour volume in comparison to the measured peak white takes a shit when BC is on. Hence, unusable to me.
Sorry for the late reply. I have been away for a couple months. No I don't have those sweeps yet. I only did quick measurements using UHD discs since as I said, I don't have a pattern generator at the moment. I did not do a saved workflow as at the time it was only for testing of the theory. I stumbled onto this tracking fix and then dismounted my LK990 to send to BenQ for FW updates while I was away. I still have not received it back here since I shipped it back from PA. I couldn't do any calibrations there because I didn't have any of my gear whatsoever. I was even compelled to buy another Sony X700 and HDFury Linker so I could demonstrate LLDV on the LK990 to Aztar. He can comment on colors, etc., but there were many issues uncorrected when I went there, due to not being able to calibrate or use a custom LLDV profile on the Linker like you can on the Vertex2. I should have my LK990 on Sep 2 according to FedEx.
To answer your color volume (mis)information, I have explained this previously on many occasions, both here and on AVSF before everyone's concerted efforts to have me banned there due to the their ignorance of facts such as this and many more.
Here is but one instance not long ago in May, before said ignorance leading to that thread to be closed too:

......WRGB OLEDs come to mind due to their white pixels being mixed in with the RGB, where you have to lower Y luminance so much to get full 3D color luminance measured properly. Javs saw this and complained that he had to turn off Brilliant Color, which I disagree with when done properly in the end. These projectors were engineered from the ground up, taking this into account, as the Delta/Vivitek and Optoma engineers told me. This is the same with the WRGB OLEDs. The LK990 with it's RGBY (Y being derived from the phosphor wheel, excited by the blue lasers) imparts similar issues, as you, me, Kris and Javs have all noted when measuring the LKs.
The issue on projectors which impart RGBY laser phosphor/color wheels aren't as widely known, but it is certainly in the same vein as WRGB OLEDs, and as such you have to compensate for this with some special offset settings when calibrating, as you can see here in the dropdown in CalMAN when setting it up, preparing for your calibration session, just as if you were calibrating one of the OLED (White) displays which react in a similar manner:

So it was you, not me who is and was wrong, because you apparently never selected the proper "Meter Mode (Target Display Mode)". In the case of the LK970/990 projectors, you need to select the one I circled in yellow in the image above, the setting for the "Projector (Laser Phosphor) - Panasonic RZ970" because that model also uses RGBY phosphor/color wheel.
To this end, what they also do is use Brilliant Color to expand the color saturation to compensate for the lack of color luminance (which I also mentioned many times previously), which is realized due to the Helmholtz-Kohlrausch (HK) effect, whereby increasing the perceived color brightness/luminance by increasing color saturation, i.e. - what Brilliant Color is also used for.
As I have said, this is exactly what a Delta Engineer who developed their high brightness RGBY Laser Phosphor HDR DLPs explained to me when I asked him this exact question, and reported here and on AVSF, to deaf ears apparently.
And surprise, surprise, you posted this over on AVSF. "Color Harmonizer" is just a fancy name for "Brilliant Color". I used to sell these Panasonic RZs for Audio General:

This portion of an image you shared there basically shows RGBY Laser Phosphor with their version of Brilliant Color, Color Harmonizer, effectively representing what it is I have been saying to you all, to no avail:

So thanks for stumbling onto that, sharing it and finally proving my point! :)
You may want to finally read up on this and actually learn it since it appears from reading a thread at AVSF that you're getting a similar RGBY Panasonic DLP very soon. You may also want to actually discuss this with other real calibrators like Jason Dustal, Kevin Miller, Joel Silver, Kris Deering (although probably not since he ignored me reporting this too!), etc. whom have discussed this numerous times as well, since you (and many others) don't seem to want to ever listen to me.
I would appreciate you correcting your misinformed posts there at AVSF in the Older DLPs thread (quotes below), saying that it was me who was wrong, continuing to deface my name, especially when I can't reply back now, mostly due to similar misinformation and apparent lack of calibration knowledge.
This is exactly what I measured on the lk990. It's colour volume is crap. Dave Harper told me the 970 didn't suffer it, quite adamantly at that but never substantiated it with measurements. It just shows he was wrong also.
On the lk990 you can turn off brilliant colour and measure correct values but the light output is 40% lower. Seems like you do indeed have brilliant colour hard coded on.
Everyone (mainly Dave) was always telling me I was wrong. Thanks for showing I was not.

Yah, the bar is low given what the LK990 did, and to be frank, if its even similar, for the price its quite good.
Here is some additional info pertaining to this, as it relates to WRGB OLEDs which impart similar issues as RGBY Laser Phosphor:

LG 2019 OLED TV's feature a 'Peak Brightness' control. The default setting for HDR10 mode of Peak Brightness is 'High', which will provide the highest panel peak luminance output when you will use it with custom PQ curve parameters values.
(https://ci6.googleusercontent.com/proxy/F1YL6DHM3CaXY2SiJyvk_hdgN5bCFCSOWviErWVh6qtKeC0PaQ-aDK8qoMl0WG3TrP8p6NELcQrvTegTCFxmjwsQu9SSwFox8_gAufJeX3rERiXRVSooiIgt=s0-d-e1-ft#https://displaycalibrations.com/images/LG_2019_OLED_Peak_Brightness.png)
Peak Brightness control provide the capability to change the amount of White sub-pixel 'boost'.
The White sub-pixel can't be permanently disabled when you will set Peak Brightness at 'Off', but setting to 'Off' it will significantly reduce the panel peak luminance output.
While the peak output will be reduced, the color accuracy will be increased because saturation distortion will be reduced in the result of less color reproduction errors.
In a display, a 'pixel' is a collection of individual display elements that, when taken together, are able to reproduce the full-color range of which the display is capable.
The LG OLED WRGB displays implements white with target peak luminance higher than maximum luminance using three-color subpixels (W/R/G, B/W/R, G/B/W or R/G/B) among four-color (W/R/G/B) subpixels in order to adjust a color temperature.
In order to enhance the luminance of the LG OLED TV, especially for HDR mode, an additional a W sub-pixel (unfiltered transmitting white light) has been added to the other three sub-pixels (RGB) which are filtered.
The unfiltered White sub-pixels are much more efficient than the RGB-subpixels, so efficient drive schemes based to 'White Replacement algorithm' utilize the W primary as much as possible and the RGB primaries as less as possible, by computing and removing/subtracting the neutral luminance from an RGB triad of sub-pixels and transfer/assign it to the W sub-pixel, this method increases the overall efficiency of the display panel.
One recommendation you can test, when the maximum luminance (Peak Luminance value) of the LG 2019 OLED TV is 800 nits, to track PQ-EOTF as accurately as possible up to 540 nits (540 nits / 800 nits = 0.675). This will require to set the Roll-Off Point @ 68% value.
Another recommendation you can test, for reducing the color saturation distortion because of white sub-pixel 'boosting', is set 'Peak Brightness to 'Off' and then measure the Luminance of the display primary colors, using 10% Window (L32) patches with 100% Luminance level, then sum the Y (luminance) of primaries (Y of Red + Y of Green + Y of Blue) and after the summary, use that number as 'Peak Luminance' parameter value and apply 'hard-clip' by uploading 100% values to all 'Roll-Off Points'.
Doing that, you will preserve the maximum possible color accuracy and minimize any color saturation distortion effect while you will reduce your peak output and preserve a 'less-HDR-effect' as a negative side-effect.
To verify using that method that the display will perform closer to an additive display performance, where the sum of the luminance of a primary color will provide the same luminance as White, then you have to re-measure the W,R,G,B at peak luminance to verify that each primary can deliver the appropriate luminance level for your peak White brightness measurement.
To pass this test, the sum of the luminance of R, G, and B will be approximately equal to the luminance of White.
When the White luminance level is higher than the sum of the primaries, then the display is not performing as an additive.
When the White Luminance level is lower than the sum of the primaries, this likely means that there some luminance compression happening (e.g., power saving/management).
The accepted tolerance will be a luminance discrepancy of -1 to 5%.
EBU TECH 3320 (Version 4.1 - September 2019) - User Requirements for Video Monitors in Television Production, defines the technical characteristics for video broadcast monitors used in a professional TV production environment for evaluation and control of the images being produced.
From Version 4.0, it's been added a section dedicated to High Dynamic Range and Wide Color Gamut for UHD and 1080P HD Monitors.
That section splits Grade 1 HDR monitors into two types: Grade 1A HDR and Grade 1B HDR. A Grade 1A monitor can accurately reproduce all aspects of the standard it was designed to display.
A Grade 1B monitor may not be capable of reproducing the full range of color or brightness defined in a standard, but will otherwise fulfill all the requirements of a Grade 1A monitor.
This novel approach was taken to bridge the gap between what a video standard may define and what monitors currently available on the market are able to reproduce.
Grade 1B HDR monitors require ≥1000 nits peak white, but they can have reduced Gamut and limited brightness specifications. Grade 1B HDR may be withdrawn at a future date.
When a Grade 1B monitor is unable to display an input signal correctly, e.g., it cannot physically display colors conveyed in an ITU-R BT.2100 signal, it shall by default apply a hard clip of the linear display signals to the available color volume whilst maintaining the ITU-R BT.2100 white point, rather than applying a soft clip (roll-off).
For Grade 1A HDR PQ or the Grade1B HDR PQ monitors, a 199.2cd/m2 (code value 592, 10-bit full range) full screen, uniform field input signal shall be displayed without power limiting.
LG 2019 OLED TV's, unfortunately can't meet these specifications, and can't be recommended for color grading of HDR content.
But LG 2019 OLED TV's can be used as client view (review screening), onset, VFX, editing, or QC applications.
