"...thousands of songs in Dolby Atmos"
Update: I don't have a Dolby ATMOS device, but listening to the "Lifelike" Dolby Atmos Mix still sounds great on my Topping D90 MQA DAC.
Here is non-ATMOS recording for comparison:

They sound very similar, but the ATMOS recording on "Stay On" has a slightly higher background - ancillary - vocal track, news report that sounds more in the background on the non-ATMOS recording... I haven't spent a lot of time comparing, but it shows there may be differences that when played back on a non-ATMOS device may not show the effect you intend on ATMOS. Fun stuff
