Jellyfin is great for my needs, and I appreciate the effort that goes into it. Recently was having rendering issues doing HDR -> SDR tone mapping since I watch my content on a 2008 era Pioneer plasma display. I found that oddly enough while the server is pretty solid, the client experience is a bit hit or miss. I'm using the mpg-shim adapter, and I'm looking forward to them building a native app with better native render compositing.
