Guys, take a look at the colour grading and the framing of the 35mm version of JURASSIC PARK, below-
You'll notice that the matted widescreen shots are taller than 1.85:1, very close to 1.78:1 (something like 1.75:1 perhaps).
Also, the colour appears to be very similar to the 3D BD version( the latter is not as gorgeous as the 35mm version), which means Spielberg and Sherak did look into the original colour while remastering JP into 3D!
