Considering I do most of my critical listening in front of the big system, I would love a tvOS version. While Atmos can be a bit of a gimmick depending on the mix (I am here exclusively talking about listening with a full surround system, and Atmos really should not be judged on how it renders to headphones), multi-channel can be very nice for bringing the concert ambience to the listener. I have been buying multi-channel FLACs from Pentatone [1] for years, but a streaming service would be neat.
