I am going to ignore your insults you just wrote, but as to the other points, you must be kidding right, you haven't taught me a single thing.
Read your own post.
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.
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.
This is actually confirming 100% my point that when you turn off brilliant colour, it becomes accurate, as in there is NO workaround to retain the brightness and get your colour volume back. I have never suggested anything to the contrary, and yes I know where that setting is on the Panasonic already, its called white gain and comes default at +10.
How in the hell was I wrong, when I wrote this all the way along? Your post actually says this nearly a dozen times.
Your argument all along was that people calibrated around it and somehow got accurate colours with it, you said so just a few posts ago, I posted my calibration results showing it wasn't possible on the unit I had here (Its also not possible on the Panasonic to keep 6000lm and get colour volume to match peak white), and you even went further and said the issue was fixed with a firmware update on your LK...
Well sir, I ask again, please show us your calibration charts proving its 'fixed' and that this has always been misinformation, at the moment there is only one person making assertions without proof.
