Consider even the most GIANT dedicated home setting vs a commercial theater running these arrays...does anyone REALLY think it's a linear comparison and each should be outfitted similarly?
Just reeks of another "mine's bigger" contest that this hobby can definitely do without.
That is the beauty of CEDIA demos. There are several 7.1.4 demos at the show. There are two rooms with higher channel counts- PRO and Harman. PRO's demo (11.1.6) is in one of the small sound rooms, Harman's (13.1.8) is considerably larger, but not bigger then what you might have for dedicated HT (aprox 20x36). Generally, everyone who have visited the rooms and currently has a 3d system, has noticed the improvement allowed by more channels. One of my clients with a 9.1.6 configuration at home, listens often, commented on the higher spatial envelopment offered by my 13.1.8 implementation for Harman. Important to note, I had complete freedom on speaker placement (except doorways), which is critical to making this all work. Choose locations very carefully.
My takeaway from designing many systems, all with various constraints, given all things being equal (speaker type, etc), more speaker locations do equal better envelopment, bigger sweet spot area, better spatial resolution, better experience. Speakers disappear, you are in the bubble. Very hard to get that right with 7.1.4 over a listening area beyond one or two seats.
And yes, one could say I'm biased, as I've had the pleasure of using and designing and tuning high channel count systems for years. Planetariums- which have been doing 3D sound for decades, have lots of speakers, and we are now finally bringing that experience to the home. What a great time to be participating in this new era. I look forward to the time when our technologies become more affordable so more people can enjoy them. I'm hoping Moore's Law will come into play sooner then later.
