Yes! I'm a bit surprised it's still iPhone-only. I was in fact listening to classical music in Music on my Apple TV only yesterday (and found a nasty bug where it wouldn't play the track I asked for, which I should probably report). I was doing this because Dolby Atmos tracks AirPlayed to my Apple TV + non-Atmos receiver come out only as stereo, but the same tracks played in the Apple TV Music app come out as 5.1.
