Here's what I learned the hard way. I put ceiling Atmos speakers in and they are too close to become diffuse and give the air you need. I switched, painfully running additional wires, to Elac Atmos upfiring speakers and that was the solution. When I sat through the demo, twice, at RMAF, I asked about why my setup was not delivering the same performance. Demonstrator explained by distance was too short. I could literally stand in the back of that room and experience how the sound enveloped you, so right there I decided to get two pairs of the small angled Atmos speakers and they work fantastic. I am doing 5.2.4 and I put the Atmos speakers right on top of the front towers and right on the side surrounds. Bought the Atmos demo disc on Ebay they used at RMAF and was wowed after I let the Yamaha run its set-up.
