I have purchase dolby vision dark, hdr and its very good. I check with Games of thrones 4k and the TV its very good. I also purchase the calibrations from Hungary from Viktor (you see the C835 made by him on youtube with a lot of informations). From Kiki i purchased and the TV was calibrated on theres room. From Hungary, Viktor calibrated the Tv and then sell the options that his do. Anyway im very happy with what Kiki/Marek calibration.
As information after calibrated my TV:
(I always measure most of the presets. Then I start calibration on the one that is the closest to the best settings. I can send you your tv pre-cal charts to show you how they looked before. We went with delta 2000 error in DV from avg 9.2 in the auto setting to 1.9 after calibration. As for HDR10 the error was 6.7 before and 0.7 after. The ISF Foundation says that the human eye cannot recognize the differences below 3 - so in both cases we went much lower. What's more, max error in your tv is only 1.4 in HDR10 and 3.3 in DV, after the calibration. Before it was 24.6 in DV and 12.2 in HDR.)
I didnt have xbox to check the game aswell. Will be later.
