Nope, it's exactly pixel art, because in the real world pixels were never simply point samples - indeed, few things are because they're not physically possible.

Nope, it's exactly pixel art, because in the real world pixels were never simply point samples - indeed, few things are because they're not physically possible. (It's a reasonably approximation for audio, mostly because there's a truly massive amount of oversampling happening behind the scenes to make it work.) Pixel art takes advantage of the fact that pixels are not point samples and never were.
