Well, only The Dark Knight (and also one of the Transformers, right?) did the stunt of shooting a few scenes in Imax 70/15 (65/15 )
For all the rest of the movies, Imax just takes the digital files that make them up (remember, even 35mm-shot movies get scanned and edited/colored/Fx'ed/finished as digital intermediates) and they denoise them, upscale them, and, in the case of Potter, fake 3D for a few scenes before printing the movie out to 70mm stock.
If you are lucky and start blowing up a 4K Digital Intermediate, then good for you as your average multiplex is 2K-only (except, i.e., Sony).
If you start with a 2K DI, which is the norm today for 95% of the movies, you can still get a tiny quality advantage as you are using the "pristine" DI which, after all the processing and upscaling and printing to film, keeps a large part of its quality while some of it is lost in the JP2K compression, potential scaling and convertion to DCP.
But we are talking very small quality gains. Tiny-tiny.
