Trying to understand if the Youtube Dolby Atoms demos are truly being sent Dolby Atoms. I have a Vizio Elevate sound bar that rotates the speakers to a up position when playing the Dolby Atoms. This works with Apple TV and Apple Music, but when I play the Youtube Demos it doesn't rotate the speakers. I do get the "Surround sound" through my speakers. The same problem with Prime Videos and Dolby Atoms movies. I don't have Hulu or NetFlix.
