There are all kinds of theatres that call themselves 4D or 5D. Smells, moving chairs, mist, fans, temperature stuff... There is no standardized definition for it.
What I'm trying to say is smells in cinemas are really niche because consumers don't demand it. Consumers don't demand it so hardware manufacturers barely make smell sensors. Hardware manufacturers barely make these electronics so AI won't use these electronics.

Makes sense, I still think there would be demand for an autonomous police dog if it could smell like a real dog, but that's pretty niche too.
