[FEATURE REQUEST] Dolby Vision support for MKV on Apple TV 4K

A quote from the Plex Fireside in the Forums thread:

@chrisallen

Currently, we support Profile 5 files by using AVPlayer (Apple’s native player) as the playback engine. It’s likely that we’ll do the same for Profile 8.1 files in tvOS 17 once we add support for it. Initially, this support may be limited to MP4 files, as we work on improving how we handle MKV content that currently requires direct streaming for AVPlayer support.
