Has anyone enabled this option on iOS 15? Im trying to figure out why it would be useful. If I airplay a song from my iPhone to my HomePods (which are on HomePod OS 15), does the song have to be downloaded to the iPhone in Dolby Atmost to play it in that quality on the HomePod or will the HomePod automatically play it in DA if the song is available in the quality on Apple Music? Otherwise, I have AirPods Pro, but I understand they don't support DA. Any thoughts? Am I missing something?
