There's a 4K version out that does interesting things with colour grading, here's a post I found: https://www.reddit.com/r/Terminator/comments/d65pbi/terminat.... The one on the left is the remaster.
There was similar outrage (if that's the right word) about a Matrix remaster that either added or removed a green color filter, and there's several other examples where they did a Thing with colour grading / filtering in a remaster.
To me, that just looks like what happens when I try to play HDR content on a system that doesn't know about HDR. (It looks like you're watching it through sunglasses.)
