This guy argues, well he makes several points but a main one being that Atmos is about gatekeeping. I agree with him that much of this is about the Benjamins: what new gimmick can we come up with to extract more profit from the public.
As for the “immersive” experience, I’m already getting it from two channels and a strategically placed sub. I’ve had visitors who have come to my place, listen to my audio system for the first time, and walk out with tears in their eyes, saying that my system sounds better than being at a live concert, it is the most acoustically dimensional audio system that they have ever heard.
Sorry but with what I’ve got, and at my age, if I’m making another audio move, if anything I’m downsizing from here. But for now, I’m more than happy with what I’ve got.
