Yup, the Begins version is closest to the IMAX print I saw. The 35mm scenes inside vaults later in the film looked much the same.
The IMAX print may have even been a teeny bit less green than the Begins IMAX clip. But it was definitely cyan/teal, it was NOT green like the other two clips.
I also definitely recall the blown-out white skies in the outdoor scenes. I also seem to recall the outdoor shots of the clowns being slightly colder too - a bit more blue/teal, not as much yellow in the skies, maybe even more of a "bleached out" look to everything.
Do you have the 4:3 SD IMAX footage that was on the older special-edition DVD?
