4K HEVC Playback - Blocky

I have a movie that I was trying to play on my 4k ATV last night and I can see it was remuxed because of audio as expected. The dark scenes were all extremely 'blocky' and didn't look right at all.

Is there anything else you'd recommend to include? I can share some screens if that is helpful as well.

4K HDR playback is still unsupported.  :( I hope it will be supported soon. :)

 

BTW to developers: Is there any progress in this issue?
