@RU.08 are you going to give both Jurassic park and Jurassic park 3 a hdr/Dolby vision grade so the awful uhd blu ray can be retired to the dust bin of garbage video transfers?
I don’t think there is any need for a Dolby Vision or HDR grade to create colour that closely matches the prints. There was no Dolby Vision or HDR in 2001 or a decade from then. While JP3 is colour timed photochemically, many films post 2001 were graded digitally and they looked fine. SDR colour with proper white balance is enough. 4K scan will ensure almost all details have been preserved. But removal of print damage is needed as the print has scratches at various sections. This will take time.
Not 2 start a quarrel but I don’t think you know how HDR works. Film (negatives and prints alike) has higher dynamic range than SDR. Higher color gamut alone would benefit it and HDR would be icing on the cake. It’s only revisionist if you make it so.
4k is only half the picture; detail. You present that in a plain SDR color space you defeat the point if your goal is to release in 4k.
There was no way to see anything close to theatrical quality in the home back when these films came out. Now we have a tool that brings us closer to that experience; to call that tool “revisionist” is, well, a misnomer.
