Yeah, my Roku Streaming Stick+ plays everything just fine. The only thing I use Kodi on my Pi for these days is anime with SSA/ASS formatted subtitles since the Roku can only handle SRT format, which means you don't get nice formatting for times when there's one subtitle for dialogue at the same time as a subtitle for a piece of text

Maybe this is a semantics argument but if you have to add something additional to the TV for it to play well then it doesnt really seem like that speaks to the quality of the TV UI.
