Dolby Surround and Dolby Enabled speakers force processing in main left and right speakers?

The Onkyo TX-NR6100 did not have a listening mode for Dolby Digital Plus when an Atmos(DD+ based) input signal was provided. The Denon receivers do give a Dolby Digital Plus listening mode along with the Atmos listening mode. You can directly compare going back and forth between listening modes, and see how the Atmos additional channels affect the soundstage.

Yeah on my newest Denon it tends to go into the Atmos sound mode even though I don't have Atmos speakers....would prefer it not do that, but...
