4K HEVC files don't work on Apple TV 4k?

If the title is in it’s original MKV container it transcodes it to h264 which pretty much destroys my cpu.

If the title is in MP$, The titles are playing with DirectPlay with no transcoding but I only get audio. I get video and audio on my Macbook Pro but when I play through my Apple Tv I don’t get any video.

I thought this was already fixed, has anyone else run into this issue?
