From the tldr’s i’ve read in the dumbsterfire that blu-ray.com forum is currently and the comparisons between the matrix that is an actual 4k remaster, these seem to be an upscale from the 2K DI with some decently applied DNR and sharpening. I like the colour timing but im kinda disappointed they dont seem to be true 4K scans.
EDIT: Wasn’t it officially stated that the non-CGI shots were scanned in 4K for the remaster?
EDIT 2: Looks like they maybe didn’t state anything about new scans. It seems that’s just what the press has been saying without it coming directly from an official source, as far as I can see. This set is looking more disappointing every minute.
