So, according to Papai2013, only the 1994 VHS release of Jurassic Park has the correct color grading. What about the 1994 LaserDisc? Is it the same as the VHS, or is it different?
Not just the JP '94 VHS, but the first VHS editions of JP2 and JP3 also contain the original 35mm theatrical colour timing, despite the image being in 4:3 aspect ratio. All subsequent VHS editions have a altered colour grading, which looks flat and colder.
I am not sure about the Laserdiscs having the original theatrical grading.
