I don’t really understand the anti-Atmos argument here. If you’re saying that very few people will install a true 5.2.4 system with in-ceiling speakers, you’re absolutely right. However, by that criteria, very few people will even install a 5.1 or even a 2 channel system for home use. The VAST majority of people will just use their tv speakers, and of those who do upgrade beyond that, most will use a soundbar because It’s relatively easy and doesn’t require a complex or expensive setup. So, by definition, in-home Atmos is really only competing for a small population of enthusiasts. Once you filter the population to only those who have already demonstrated a willingness to go above and beyond in the pursuit of a theater-like experience, I think it’s reasonable to assume a certain population will decide to upgrade just as people did when 7.1 or 9.1 or 11 channel sound became a thing. Will Atmos evolve to a point where mainstream suburban homes are adding 4 in-ceiling speakers to their living rooms? Almost certainly not, but can it and will it survive as a way to drive UHD (or similar streaming format) sales? I think yes
