Yeah, out of the box experience is terrible. I wish we could’ve installed custom ROMs on TVs too but most of them are vendor-locked. Projectivity Launcher is a life saver. Default everything is just bad. I did a similar thing and removed many apps via ADB.
For Youtube alternative, SmartTube is the best. You can sideload it via ADB.
Sometimes it might not work, and when that happens just check out a new update. It will also notify you when there is an update.
You’re welcome!
