Purchased movies only plays on standard HD.
But series on Apple TV+ has Dolby Vision playback enabled but Dolby Atmos is not enabled even though my device supports it.
Yoga Pro 9i Laptop
Support Dolby Vision/Atmos.
Even when I plugged into Atmos Soundbar. It still won’t enable atmos.
AFAIK pretty much all the Windows Apple apps are in beta and are probably missing a bunch of stuff.
