Some of my screenshots were later cropped in photoshop so I think that’s what you’re seeing. The video file has the full image shown. The night scenes are indeed pretty crushed unfortunately - added some pics of the dark shots to the same album I posted earlier:

The 3D JP release also contained a few VERY subtle CG fixes. They removed the potted tree and safety cable in the shot where the Trex flips the Explorer over, removed the fishing lines that open up the Dilophosaurs gills, repainted/replaced the backdrop sky when Alan is in the tree with the kids (it was clearly netting before) and one or two more IIRC. Very subtle fixes but tastefully done.

The cropping is indeed super close on the 3D version since they needed to cut some horizontal data for the conversion. Once I noticed how pink/magenta the 3D version is it really started to bug me.

One last example showing how ‘blue’ the laserdisc/DVD (and maybe the VHS? Haven’t compared personally) transfer is.

Here’s the 3D remaster with their new color timing:
