In case you should be able to sideload the "leanback" apk, the provided youtube is the leanback one. Some apps are unique and detect what to launch at runtime (like Play Movies), but most of them are separate apps so you can just get them from sites like apkmirror and install them

The server requires root permissions but on the Core it will run fine because I will sign the apk with system keys.

I was thinking about publishing it on Google Play, it would be my first time
