It is really a very good and immersive Atmos mix.
This is the album that make the most use of the Wides Speakers (9.1.4) of every Atmos album I have listen. Sometimes the Wides sound louder than the Fronts spreading the sound.
The mix is somehow discrete, but you don't get a particular sound or instrument in only one speaker. You get all sound spread around and really feel you are inside, not only within the band, but sometimes inside the instrument. For example, the Drums use to sound on every all 9 speakers floor level, and almost nothing from the tops. But it is not a "expanded stereo". Sometimes you feel the sound of every different drum coming from different location, as if you were inside the drum kit.
The trumpet section is at the right, but you are not overwhelmed from the right side speaker, as in other mixes with too much content on rears. Instead you feel the whole trumpet section coming from a wide area, making sound very little at the Right Front speaker, and more sound from the Wide Right and the Surround Right speakers. It seems like each trumpet is just an Atmos Object, in their specific locations, and separated. When all trumpets are sounding simultaneously you perceived the sound from that wide right area, but occasionally, when single trumpets sound alternatively, you hear each one from a slight different location.
I'm really impressed and I continue listening in Dolby Atmos. I didn't yet changed to Auro-3D to check the difference.
