I can't speak to infuse (because I'm self hosting to get away from subscriptions) but Jellyfin is extremely picky about file formats on appletv, I found myself using VLC more and more often until my Pihole sd card died and I found myself with a Libreelec box that just runs anything I throw at it without complaining.
the search for a remote half as good as a siri remote has begun.
