I was able to hear AB switching in the middle of the same material as it looped.... it wasn't drastic, just different and not in an unpleasant way.
They played the same clip twice in a row, once using the Atmos speakers and once using the ceiling speakers. No switching in the middle unfortunately. I believe I could detect a difference between the two configs in that the physical speakers seemed to me to have slightly more 'precision' in where the sounds were placed. But this was a brief demo and I would need to hear more, with preferably a blind comparison, before I could swear that I heard a difference at all. It wasn't that one was better than the other - just different. In fact, the Atmos speakers may have had a greater sense of spaciousness too, in the cave scene I am not permitted to mention by name.
The demo I attended was a joint presentation by Dolby and Onkyo and Onkyo were keen to showcase their new Atmos speakers, so there was no benefit to them to switch constantly between their speakers and the ceiling speakers.
However, on 13th August I have been invited to another Atmos demo at Dolby in London and, this time, I believe it is Dolby only, so I may get more opportunity to probe deeper. I will post my report here a day or so after the 13th.
From what I heard already, I would have no hesitation in using Atmos speakers or modules. I am only using physical speakers because, for me, in my room, that is the easier option.
