While these channels would not be Atmos channels as such they would be getting audio processed to them while Atmos is being decoded providing the channels are enabled in the speaker configuration menu. You would also need to select the relevant option from the list of sound modes when the receiver starts to decode Atmos for the first time."
My paranoia is playing up again...

That parsing would make sense to me, except for three factors:
(1) As we all know by now, there will be no PLII on these models; it has been supplanted by Dolby Surround. This may be a matter of simple nomenclature, but it implies to me a lack of clear analysis on the part of the Denon support rep.
(2) The (European model) X5200W manual (p. 287) shows that Dolby Atmos (as opposed to the Dolby Surround up-mixing process
utilize all speakers. So there is at least some measure of inconsistency between the manual and the support rep's reply.
(3) One would think that there would be at least a footnote included with the Height Layout configuration diagrams (e.g., p. 212 of the manual) to advise the user that selecting one of the pairings that includes heights in lieu of tops or Dolby speakers will impact on the true Atmos rendering.
