And I have to agree that, if nothing else, the Blu-ray version looks off. There’s too much space on the top and bottom of the picture in general, and it looks more like an open matte version than something that the cinematographer would intentionally shoot for such an AR.

This. The 16/9 works better in 3D, specially in the aerial scenes, but the film was clearly framed in cinemascope, no doubt about it. Even the virtual cameras used in the shooting had the cinemascope ratio.
