Oh my God! I can't believe my own eyes, but I think the dynamic TRC scaling is GONE!
ABL still works though, and it does affect the gamma when it limits the brightness, but the gray-scale seems to be stable otherwise (the "black pops" are gone)!
The "Dynamic Brightness" test video shows a stable gray gradient if I tune down my Cell Light to the point when ABL doesn't limit the overall brightness with the full screen bright (near-white) backgrounds. And there is no difference between black and middle-gray backgrounds with higher (~15) Cell Light either.
So, ABL is still here (and will remain here forever...), but the gamma is stable until it starts limiting the peak brightness. So users can still expect some "bright pops" on bright scenes like winter sports with a lot of white snow. But no more "brightened up grays"!
BUT IT NEEDS MORE TESTING!!!
I didn't measure anything yet. It's just my first subjective impression! (May be it's still here and only the magnitude changed or it depends on my other settings because I recently made some changes in the Top Debug Menu...)
Edit3: Sorry, I tested it with CinemaSmooth, I can still notice some dynamic adjustments with 60Hz. When the MLL jumps, dark grays follow (CinemaSmooth has more stable MLL).
