SOLVED: Can't play HDR DV HEVC MKV files

[cantcurecancer]

Actually, scratch that, there's still problems playing via the web. When I had HDR disabled on my monitor, it played fine and looked OK. When I enabled HDR, I no longer have the tint issue since I enabled Tone Mapping in the settings, but it definitely doesn't look right compared to playing the file via VLC (w/ or w/o HDR enabled). It's like the blacks are crushed and the colors don't look right.

Ugh. I'll maybe post some pictures when I get a chance and after I go thru the steps in the documentation.
