Explain HDR Source Luminosity Differences
So I am feeding my LS10500 (pixel shifter 8bit capable of max resolution HDR at 30fps) from:
A. Apple TV 4th gen. Here everything appears very dark and dim once HDR 24fps selected. 4kSDR looks very lively and well lit.
B. Sony X800. Here HDR 24p looks magnificent with medium lamp settings, great color separation and blacks,
in Passengers the robot bartender polishing a glass over a dark background as well as the space walks look awesome.
Other HDR titles fail to look dim.
To what do I owe the difference and what can I do to fix the Apple TV?
With anticipated thanks! I know I have been lurking here for decades but I am still an amateur and my brain is....
