I've got an imperfect layout and 7.1.4 Atmos works with zero complaints for me.
I've got 2x bounce Atmos and they are way more fun than without Atmos turned on. They will do in a pinch. 'Real' Atmos is way better.
For home office Atmos use I strongly recommend Pioneer Andrew Jones. Either the speakers with built in Atmos upfiring units or adding the Atmos pucks on top of speakers you already own.
