I am not so sure that HDR10 is correctly working with Mr.MC on the ATV4K. It seems to be sending "fake" HDR10 metadata. The Sony 4K Camp HDR video has totally wrong HDR10 metadata in the SEI, if you play that clip in Mr.MC the HDMI output HDR10 metadata is completely different. I tried Infuse 5 and it doesn't look like it even passes the HDR10 metadata. There are some folks complaining about it on Infuse forum. The one issue with ATV4K is that when you select 4K HDR as the display mode, a HDR10 metadata is always sent with max display luminance of 250 nits and min luminance of 0.10 nits (I forgot the exact number, have to re-check). This means that the display is always in HDR mode, but with SDR luminance.
