Why's that? Pixel art has more direct relation to the quality of the display than any other digital medium since the basic unit of pixel art AND the screen it's being viewed on is the pixel; it's a 1:1 correlation.
Wtih most of the TV-targeted pixel art you see it appears that the artists have only neglected a few steps of refinement that TV blur obscures, not enhances, but once in a while you see choices made in pixel placement and color selection that are very hard to explain in any other way than intentionally exploiting the TV blur.
It only makes sense that artists would change up their process to make the end result look good on the intended display, instead of treating it as you would a conventional monitor, which doesn't always result in art that looks crisp and has depth when viewed on a TV. Among other things, the blur causes pixels and colors to bleed together a bit depending on hue and intensity. It also makes small areas of contrasting pixels such as spot highlights darken due to the light being spread out over a larger area. It needs to be compensated for somehow.
Anyway, didn't mean to derail this thread, if I have anything else to say I'll address it in the writeup :p
