My AVR runs Neural:X but I really haven't experimented in great detail the different surround settings. Mostly due to only briefly having the old QS8s hooked up. I feel like if I leave the 10s slightly forward I will have a similar result and if I need more envelopment I can always add the rears but they would be freely hanging with no rear wall.
