How are you folks getting Atmos from Disney+? Before I set up my new theater, I bought a Amazon Fire TV that I haven't unpacked yet, since I've now been able to get the full Amazon Music service through the Roku. Does the Fire TV get Atmos from Disney+?
Did you check the info screen on your RX-A3070 as to the actual number of input channels? You may see DD+ from the Roku, but that still may be decoded as Atmos (7.1.x) in the 3070.
