It was degrained a little bit to keep a reasonable file size, but it should look about the same in motion. It is still large because it is very grainy.
Like the theatrical and DVD releases, the BD is in widescreen aspect ratio. The film was made in standard/full screen aspect ratio, so compared to the LaserDisc release it is cropped on the top and bottom.
Source/encode comparison if you want to compare the amount of grain.
