I grew up playing DOS games on a VGA CRT, most of which were line-doubled 320x200 resolution. The pixels were much sharper than you'd see on a cheap SD TV, and not far from the sharp edges of nearest-neighbor upscaling, which is my preferred style. I also point out that some official artwork for old console games showed sharp pixels (e.g. the Super Mario Bros. cover art). Calling it "false nostalgia" is making assumptions about the hardware of the time and the artist's intentions that aren't universally true.
