You basically form "dome" of sound above both MLP's with speakers forming a rectangle that's 8 ft wide, 12 ft long, and actually meeting Atmos elevation specs for both MLP's. I prefer to keep this rectangle smaller rather than larger to maintain image clarity and stability on top, at the same time keeping your ceiling speakers not too off-axis.

This is why I am so afraid of lawyers
and your elephant-grade memory and documentation; where did you dig up my post from? I don't even remember I wrote it :-). Anyway, there are multiple issues and considerations too complicated to discuss in details here so I'll try to sum it up, all in my very humble opinions (any expert pls correct as needed). Bottom line IMHO is NO change to the above setup. Some considerations:
How is Auro is different? Essentially, it wants
2 WALL, not ceiling, speakers above your front speakers, and 2 wall speakers above your rear surround speakers. All of these are at 30-40 degree elevation, hence wall instead of ceiling, although you could probably get away with putting them on ceiling, a compromise. (This difference is semi-incompatible with Atmos.).
It also wants a VOG right above your head. This is critical for Auro because it uses wall speakers and leave ceiling "uncovered." (Complicated but this difference is mostly incompatible with Atmos x.x.4 setup.)
The battle has already been decided so overwhelmingly in favor of Atmos that regardless, the system should be optimized for Atmos - which is what I posted above. It makes even more sense because Atmos setup is compatible with DTS:X. Auro is like an orphan with their 30 degree high wall speakers. Bottom line: regardless of SSP, to me top priority is set up system to be best for Atmos
I don't think your ceiling speakers (pointing straight down and not aimed at listener) should be too much off axis, again making above Atmos setup with top layer speakers around MLP's head better than Auro setup where top layer speakers are on further away on top of main front and rear surround.
There are 2 main components of Auro: Auromatic the upmixer
and Auro the movie codec
. So assuming you keep the Atmos oriented setup, what's the price you have to pay?
Auromatic is to me more valuable since people *seem* to like it for upmixing music, and, being ambiance oriented (as opposed to specific gun-go-off-in-the-corner precise sound objects), with top layer a duplicate of lower layer, is good enough with your Atmos setup. ie Speakers not being in 100% precise position is acceptable/Ok for ambiance sound reproduction IMHO.
The Auro movie codec OTOH is compromised, but this codec is, IMHO, deader than a door nail
:-), so not being to reproduce it exactly shouldn't shed any tears.
FWIW I do not upmix music (Auromatic hence not needed), and don't worry that there would be ANY serious movie that doesn't have Atmos or DTS so Auro is also out. ie I don't even want or need Auro in my CB IVa.
