Can't find Dark side of the moon in dolby atmos

Hello everyone
I know for sure that some time ago in the apple music catalog there was a dolby atmos version of "the dark side of the moon" by pink floyd, it was mixed in dolby for the 50th anniversary. Unfortunately now it only show me the "hi-res" thing and not the "dolby" one.

Does anyone know why it is like this? Or if the dolby version will return?
