It would depend on what aperture plate was in the projector at the time? I got to see it on 35mm back 2006, and while technically framed for the 1:85 screen in the theater, the extra picture info was faintly visible above and below the screen.
The airliner in flight shot on the 4K is cropped where previous editions have not.
Here’s a 35mm frame for you. Not the exact one, but pretty close.
