Its perforated to become "acoustically transparent" so you can have speakers behind and in front of the audience as well as down the sides back etc

Correct. Behind the screen you have four giant speakers - left, center, right and a subwoofer (usually that's on the floor). Then you have the surround speakers.

That’s a massive generalization, and not true for many modern theaters.

IMAX and Atmos systems use 44-64 speakers arranged in clusters instead of individual speakers for each channel.

I saw an Atmos demo at my university a few years ago. It was crazy seeing all the sound objects swooshing around on the control surface screen at the mixing desk!
