FWIW I've never had trouble with the subtitles in Jellyfin on the Roku app, or on Infuse (AppleTV client). In fact I've practically never had any kind of trouble at all, aside from my Roku devices not supporting h.265 encoding.
Android TV (a Shield, in my case) did have bad audio sync problems with several common audio codecs. My bad for trying to cheap out, should have just gotten the AppleTV to begin with. Bites me in the ass nearly every time I try to save money in that way.
