I'm having the same issues on my two Roku Streaming Stick 4K devices. Super saturated high contrast images where people's skin looks almost red, this happens only when streaming HEVC mkv files on the Plex app. This does not happen when I stream those exact same files on my Fire TV devices nor does it happen when I stream those same files on my Roku Ultra players I bought back in late 2017.
This issue is ridiculous and the way Roku responds in these threads is frankly a complete joke! Moderators here who speak on behalf of Roku act as if they haven't read through the original complaints at all, they keep asking us to enter the same information again and again and act as if every problem is a device specific problem when it isn't.
We need some REAL customer support from Roku! The people responding here on behalf of Roku KNOW NOTHING! It's painfully obvious that all they are doing is copying from a script of pre-written troubleshooting responses they were given and then pasting those same unhelpful responses over and over again to us. We need people with brains who can think! Not robots who simply regurgitate the same unhelpful responses that were copied and pasted!
Not trying to be offensive to anyone personally, but my god it's like this on all the topics I check when customers have a problem. Roku, get with the program and fix this issue! If I can stream these HEVC mkv files on a Roku device that is 6 years old and they look normal why the heck do the same videos look messed up on a more modern device?
This is completely unacceptable and so is Roku's response to it, which has been literally nothing helpful whatsoever! Just like all the remote issues!
