You are right! What a convoluted, non user-friendly way to find an Atmos version of an album.
Listening to it in Atmos now - the problem with comparing it to the Apple Music version is that Tidal Apple TV plays back Atmos mixes at extremely low volume. I have to take my AVR to +6 dB to get a decent level, and then still not as much as I'd like - my AVR (Pioneer Elite XSX-LX505) maxes out at +6 dB
I have the VSX LX505. It maxes out at +9 and I've had it there for some of these Atmos mixes. It sounded good- surprising for being maxed out- but I wouldn't want to run it wide open for any amount of time. But I kept it at +6 for quite a while. It was certainly nice and loud, as loud as I usually listen, but next to no headroom if I ever want to really crank it.
Then I switched to a Talking Heads Atmos mix and it was blaring; had to turn it down quick. That mix sounded good still in the negative, though still higher than I've ever had to listen before. But there's quite a bit of variation from mix to mix in Atmos.
