Tested with LG 65B8.
I think you are confusing Tone Mapping on a media player with its ability to pass thru MaxCLL/FALL HDR Infoframe data from HDR video sources.
The Apple TV 4K does not do MaxCLL/FALL HDR Infoframe data passthrough.
Tone mapping is what a 4K HDR TV does with HDR video and Metadata to map such video to each 4K HDR TV’s individual display characteristics.
Even then different TV brands all go about Tone Mapping differently. So results will vary for differing combos.
I’m not seeing drastically different 4K HDR picture outputs when using say an Odroid N2 vs an Apple TV 4K (MrMC) in combo with my Panasonic GZ OLED TV.
There is a detailed post about Tone Mapping here: https://forum.kodi.tv/showthread.php?pid...pid2897271
Ok, you are right, but the ATV clipping the HDR content above 800 nits. This is wrong.
Try with Spears & Munsil Demo.
