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.

There's multiple versions of the Matrix on the trackers and the internet that I know of. The official release all look kinda different to each other:

There's a 35mm scan floating around from a faded copy with really weird colors sometimes

And there's an Open Matte Version, which I don't know the Origin of.

For me, it's the Open Matte that I consider the ultimate best version.

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.)

That is precisely what this one was. The OP posted a follow-up comment at https://www.reddit.com/r/Terminator/comments/d65pbi/comment/...:

> I have an updated, I found out that T2 4K is an HDR movie that needs to be played with MadVR and enable HDR on the TV itself, now the colors are correct and I took a new screenshot: https://i.imgur.com/KTOn3Bw.jpg

> However when the TV is in HDR mode the 4K looks 100% correct, but when seeing the screenshot with HDR off then the screenshot looks still a bit wrong, here is a screenshot with correct colors: https://i.imgur.com/KTOn3Bw.jpg

I own the blu-ray of The Terminator 2, and briefly owned the 4k as well. The 4k looks like dogshit, with or without HDR enabled. This is largely due to the film using DNR to remove film grain, which they did for the 4k transfer was created for the 2017 3D release (film grain is bad in 3D I guess). The transfer is also much, much more blue.
