Just wondering if the recent Roon API has made this closer to a possibility. I don’t have the talent but I wonder if someone talented out there is working on a basic Remote Remote app for the Apple TV, just for basic cover art to fill a big TV and play/pause/next/prev track. Just basic functions but it would look great to have cover art filling the big screen.
Note this would be different to mirroring an iPad or iPhone screen because it would control playback of the core to any endpoint if required, not just to the Apple TV which is limited to 16/44 PCM audio.
