That's true! Silly me for not even having considered this at all yet. Will pull the wire for 7.1.4, regardless if I go 5.1.4 or 7.1.2.

It's open concept, so I've got only two walls in this corner - TV wall in front where the KEF LCR is and a left wall, where the right wall is a bit further away than this "room". This "media room" is planned to be about 12ft x 13ft. The actual back wall is about 40ft away in the back.
It's why I'm doing the Atmos and surround speakers only in-ceiling. From what I've researched, surrounds need to be elevated anyway, so what's another couple of feet
Although I could probably convince the wife to accept a design with speaker stands all around, logistically, I also prefer the wire being run via ceiling than under the wood flooring.

Given the choice, I would go with 7.1.2 because it provides more even coverage than 5.1.4. Aside from the L/C/R speakers, you have a pair of speakers anchoring sounds to your sides, a pair of speakers anchoring sounds behind you, and a pair of speakers anchoring sounds above you.
Ah, okay, perfect. Not losing any sound information is great. With this knowledge, then I'm leaning even more toward 5.1.4 than 7.1.2. My reasoning...
If we don't lose the sound, I am thinking placing the side speakers about 110 to 120 degrees from the TV listening position instead of 90 degrees to the side. Then it's still slightly located in the rear carrying all the sounds, even though not its own discrete channel.
In 7.1.2, having only 2 Atmos speakers and pretty much have to place these two speakers directly above the viewers trying to provide both the front/rear effect vs. having 4 Atmos speakers where I would have the front and rear Atmos discretely separated. The surround speakers carry both side/rear channels, so if it's slightly angled to side and
rear, it compromises to be able to provide effective immersion.
Comes down to legacy and existing movie soundtracks are designed for 7.1 vs. what I speculate future soundtracks will have more creative and dedicated Atmos content, so it's why compromising the side/rear surrounds instead of compromising the Atmos.
Actually, as part of this exercise, researching further into Atmos, it's completely different algorithm and design from the legacy discrete channel design. It's object based and truly 3D sound. Actually, I'll stop writing there... as it'll get off topic into how the channels are used now vs. TrueHD, so probably a another thread for that.
