It's most likely because the game seems to use the textures from an existing installation. You can't just enlarge textures and have them look the same.

I'm sure they could do some AI upscaling, but that probably wouldn't improve the situation much. GSG tried that for the Definitive Edition, and look how that went.

It would be interesting to see a new texture pack made for it, which focuses less on nostalgia and more on fidelity.
