I believe they use three chip DLP systems.

The better Cineplex's use the Sony 4K LCOS projectors
(I've compared these to theaters w/ Christie 2K DLP installations)
They should really use 8K but no-one wants to build one as even Sony often loses money.
Would be hard to display 8K due to lens errors and focus errors over flat screen?
Also new screens not as large as old 70mm era (curved screens, better lenses)
as 70mm would be like 8K resolution at least.
