Some think so; others aren't convinced; I'm on the fence. I find that the height channels consist mostly of fronts and rears doubled at lower volume and/or with added reverb. It makes for an "immersive" experience, I guess, but it's more "enhanced 5.1" than "reimagined-for-Atmos." YMMV.
A fair amount of existing discussion about all the TH Atmos mixes:
