Not only are the JP 35mm stills gorgeous in terms of colour and definition, they have a much better framing than the 2D and the 3D Bluray.

The 35mm stills even in the matted 1.85:1 widescreen shots, are both wider and taller than the 2D and the 3D BD. It seems as if they cropped the original widescreen version to 16:10, then put black bars on top and bottom of that 16:10 frame to create an even more cropped 1.85:1 version. Its like double-cropping!

For the 3D I can still understand that they had to shift the images left and right (still it doesn't justify that much cropping as Titanic 3D-the scope version that played in theatres, wasn't cropped much from the framing of the DVD), but why was the 2D cropped?

I just hope one day to get my hands on a 35mm copy of JP so I can preserve the uncropped version, as it seems, Spielberg or Universal won't invest on a remaster anymore after their 3D version was a success. So each successive home video version may feature the cropped framing.

Please do not forget that, in film projection, some cropping is inherent to the projection process, assumed to be taking place by the filmmaker, and thus compensated for when filming. When transferring to home/digital media, then, some cropping is appropriate, in order to reproduce the image actually seen in theaters.
