I just upgraded to iOS14 and tvOS14 yesterday, and was watching a 4K movie from the Apple TV 4K. My internet has been struggling lately with 4K bandwidth requirements, so I thought I’d Airplay it over from my phone because I knew that Airplay was limited to HD streams.
All was well, the picture was good (but I don’t think 4K), but was surprised to see that my Arc under “About My System” said “Dolby Atmos”, without the “(DD5.1)”.
Nothing on Apple’s site seems to indicate that this was coming. Or am I imagining things and this was the way it always was?
