I just did a quick compare to the SACD. The DSD still has a lot of presence and clarity. The mix is a little different with Atmos though. I had not noticed it, but on Time, the last clock chiming is in a different location. There are a number of small differences like that, but the overall presentation still has the same effect. The laughing moves around the back of the room and then to the center on the SACD while in the Atmos mix, it hangs above you in the rear, then moves front. At the end of Time, there is a woman saying "I never said I was afraid of dying" coming from the right rear and it is so clear and distinct that it surprised me and I had to look, BOTH times I listened to it lol. The SACD always felt spacious and it actually has more separation than the Atmos mix, but the Atmos mix feels huge and has more presence in the room.
