So, 2 different masters, most likely different in framing and obviously definition, the old one plagued with edge enhancement and not the new one. I watched it here and there, and have not noticed color artefacts. I don't know if this is the same method you used here, but if it's not, you might want to look into that for a better rendering of True Lies. Just a thought.
That was me. 
The problem with that method is that it's rather slow and it's not possible to do anything much scene-by-scene, as spoRv's method does (unless you have an immense amount of patience). So what I did was to just take a few screenshots from the UHD and a few from the Blu Ray, matching them up framing-wise, then putting them all into a single image, and let the tool auto-generate a 3D LUT for that image. It worked well enough here, but when the masters are too different I think it doesn't hold up too well.

Then what about trying your method using the 35mm and the D-Theater of True Lies? They'd be both in 2.35:1, right? Might worth giving it a shot.

Well, it's not really "my" method (aside maybe from doing it on an UHD, but that's not really that special). You can try it yourself. Not enough of a fan of True Lies to do that personally. Mummy is one of my favorite movies and it was a special situation because the original Blu Ray looked horrible but the UHD got a new transfer.
Edit: When I said "too different", I meant colorwise. The framing doesn't really matter that much. You just need areas of the screenshots that overlap so you can have the tool create the 3D LUT.

I've been doing exactly the same as TomArrow using DrDre's tool. I'm using Photoshop's Auto-Align function to align two frames from different sources and crop the frame they share

OK, I deleted the actual lossless file, and I'll work on it again in the near future; this time I'll follow the feedbacks, hoping to get a better result - we'll see!

Well, I am so not the tech guy to do so. I wouldn't even know where to start. Whenever I see you guys sharing avisynth scripts, I'm like "nope, not for me. Might as well be written in Korean".
Since I have no idea how these things work, here's a thought that is probably wrong, but hey, I'll share it anyway: what if you/someone/whoever uses your method using a shot or maybe a couple of shots that capture the mood of each scene or scenery, and put them all into that 3D LUT thingy, woudn't that end up being pretty close to the expected result?

Haha, I see.
That might work; that's what I meant with "a lot of patience". Making one of these LUTs takes a few minutes. Making a hundred AND applying them one-by-one, not mentioning aligning the shots ... let's just say I'm too much of a lazy lizard to do that.

That would still be a lot faster than a shot-by-shot color correction, right?

That's how I do it. Shot-by-shot color correction. Thousands and thousands of corrections. It's liberating, give it a try sometime spoRv

Now I'm focused on AAP-AR projects, and I don't know if I would patient enough to make a shot-by-shot correction - even if, when I think I made HP7 and set 700+ cropped shots by hand, well... maybe I could be crazy enough!
