What I am curious about is how a BR looks up-scaled vs a 4K disc.
See for yourself this Sat. !! But upscaling doesn't provide a WCG or more headroom on the disc, or less picture noise, or more actual picture information, so I generally don't bother. Pouring 2 Buck Chuck in a Chateau Petrus bottle doesn't make it taste any better either, unfortunately.
most of the time the BR will be inferior to teh 4k disc (actually I have yet to find the opposite true)but a BR will 100% look better on a 4k PJ than a standard PJ (in my case the rs400 vs the ae8000)
I kept my Oppo BDP 103 Blu Ray player, which has been handy to play the Blu Ray on and compare the 4K UHD BR that's in my Samsung 4K player. What I've found is that a " sharper picture " is not the main improvement ( some of these recent Blu Rays are plenty sharp ). A cleaner picture with much less picture noise, improved picture detail over the Blu ray, and a much more refined color palette is what I notice. Things just look more realistic ( not using HDR ). True, it's not perfect without having full blown 4K calibrating software, but it is a step up. I don't mind re - buying some movies, but mostly I will be buying new movies on 4K UHD BR going forward. Any improvement in the source material is welcome. You can buy better and better projectors until you turn blue in the face, but the source material will always be the limiting factor. That's why I got rid of all my DVD's ( except Team America, World Police, since the Blu Ray isn't the " unrated version " ).
A interesting test would be to calibrate Blu ray, and UHD to have the same gamma performance, i think a lot of the wow comes from the much higher gamma mastered on UHD discs, wich im sure you noticed when comparing BD vs UHD discs, even when displaying the UHD as SDR Rec 709. That means that colors look more saturated on UHD, more colorfull, so if your to compensate for the different gamma in the mastering you will have to calibrate a much lower gamma for your UHD settings, or a much higher gamma for the BD.I think its hard to point the differences you experience directly to WCG or HDR, with very differently masters..There is no doubt that higher resolution and a bigger color gammut is a good thing, i just dont see any signs of people having controle over it, i dont see anything but subjective opinions, who tell that its wow, so im thinking.. Hmmm wonder what they would think about DB if they calibrate a 2,8 gamma curve, and crank up the light output, that sure makes it more colorfull and dynamic.
We just need calibration software to catch up. But in the mean time, I feel like I might as well start acquiring 4K discs. Hopefully 2017 sees 4K UHD calibration solutions become wide spread. And yes, there isn't the same kind of standards and "control " we have with 1080p. It's like the early days of HD DVD and Blu Ray. But no one is going to die if things aren't perfect. It's just somewhat annoying. Anyway, only around 3.5 % or 4% of my source material is 4K at this point !
watched Xmen:apolcolypse againone of the best looking discs hands down...man its good
I have that disc. It and a few others are sitting unopened, waiting on the Oppo. I have seen the movie, but not in 4K with Atmos. Looking forward to it and several others.
