Unfortunately, I do agree with you. I think the screenshot used in the meme had gone through some sort of AI upscaling. I found a Blu-ray rip of this film and skipped around to what seems to be that exact frame.

• As you mentioned, the hair is more feathered and less solid
• The skin is more textured/wrinkly
• Even the background is changed. The cat decal has more imperfections, the menu on the wall became just a dirty cupboard or something, and there is inexplicably a TV with a stack of video games added out of nowhere.

It is possible that I am just taking this still from a file that is an old rip of the film, and that these changes that we see in the meme were part of a manual remastering effort for an official tenth anniversary rerelease of the film or something. But I think your assumption of this being an AI upscaling for the sake of the meme is more likely.

EDIT: I see that there is a stereoscopic 3D version of the film available. Again, it is possible that the differences we see here are from the 3D version, but I doubt the differences between these two versions were that drastic.

EDIT: Nope, the 3D version looks just like the 2D version.
