You're welcome. I emailed Turner Classic Movies for information as to what would be shown in this 40th anniversary presentation, and they told me that it would be the new 4K scan that was recently done.
Here is an excerpt of an article that talks about that new 4K scan:
"For this 4K presentation, the Theatrical Version was scanned in native 4K from the original camera negative (at EFilm in 2018), was restored by Fox (at Company 3/Deluxe Entertainment Services Group, supervised by Ridley Scott and Pam Dery), finished as a 4K Digital Intermediate, and graded for high dynamic range in HDR10 and HDR10+ (for the rare displays that support it, but if you have one this should make a big difference for you)."
Underlining emphasis added by me.
One thing I did notice though is, the movie that I saw today was presented in a flat aspect ratio instead of scope.
I think that because this new 4K scan is primarily for a product designed for home TVs, they cropped the sides of the picture to fit the dimensions of living room TVs.
On the other hand, most movie theaters these days are common width, not common height, so the flat aspect ratio is actually a good fit for modern theaters as well.
I was a little nervous about the picture quality right at the start, because the Fox logo at the beginning was pretty low resolution. But I needn't have worried. The movie itself was great (within the limitations of the movie cameras that they originally used of course).
By "logo" I mean that thing with the searchlights when they play the fanfare:
