I could have sworn there is something official stating support for 10-bit on the 4K Fire Stick. Arguably the plain 1080p Fire Stick should too beginning with the 2020 revision, since they started using the same SoC on both then. At least it’s smart enough not to try playing 4:4:4 color sampling.
If you go back to my original topic on it, I think it comes down to color space and ranges tagged in the stream in a way Plex can see. After I posted last night I came across a couple other shows on in my library that are direct-playing correctly with subs.

So the question is how other players deduce this info when it’s not present (or maybe they just assume a bt709 color space for content of 720p or higher and bt601 for standard def – that sounds sloppy).
@sloke123 We’re talking about 10-bit H264.
