Would love to use the Apple Music app on my Apple TV 4K to view album artwork and live lyrics, but when I do, the music playback is a more ambient surround effect versus listening in full by streaming directly to the speakers.
Don’t think this is currently possible, but would love to be corrected or submit a feature request.

Ah. Yes, that’s a good point I forgot. Because you’re using the Apple TV to stream the music, it’s going through the TV (HDMI) input, and the ‘full’ setting is only for streaming, not for the TV input.
Not sure there is an elegant solution to this, but you could instead try to change the output of the Apple TV from the HDMI stream to an AirPlay 2 stream to the Arc. That would, I think, make the ‘full’ setting work, since you’re no longer using the HDMI input. I’ve never tried this, but in theory it should work.
