The same art style was used on portable consoles with LCD screens, and on line doubled VGA modes with blocky pixels. Even pixel art designed for SD televisions and low quality interconnects might not have been intended to be blurred, e.g. Chrono Trigger includes a pixel art typewriter in the starting room, where the keys are represented by a single-pixel checkerboard pattern that is easily made unrecognizable by blur. Some designers even showed blocky pixels in printed materials, e.g. the cover art and the instruction manual of Super Mario Bros. It's possible that some artists intended their pixel art to be blurred, but it's not universally true.
