Pixel art is defined by treating pixels as little squares. There is no single native medium for displaying pixel art. The same techniques were used for games on portable systems with LCD displays. Additionally, there are many examples of printed art using blocky pixels. The Nyquist limit is irrelevant to pixel art, because the Nyquist limit applies only to reconstructing signals from point samples. Using pixel art on a monochrome LCD (no subpixels), I can display signals with maximum frequency limited only by the sharpness of the edges of the little squares.
