Honestly, for running jellyfin/emby/plex, there's nothing better. The only thing an update might get you would be higher refresh rates or maybe 8k support, but for watching video, who cares?
Once I disabled the built-in "leanback" launcher with its fucking toxic ads and replaced it with flauncher, it's been essentially perfect for watching media. flauncher is fugly as hell but it stays out of my face, unlike google's ad-focused launcher.
