Bought the Special Edition a few hours ago. It looks like it’s same scan used for the Blu-Ray without the matte. The colors are still way off from the screener and the dynamic range is crushed compared to the BB disk. There also seem to be a couple of IMAX shots that aren’t on the disk. Mostly establishing shots (Wayne Enterprises, Fox getting off the copter, the Batsignal going off). At least that I didn’t notice in the five minutes I’ve had with it yet.
The shots for Rises are superb. If it turns out to be quick and easy, I may go ahead and add those shots to the movie for a true IMAX version.
