One thing I like about my Gameboy 3DS is that the display is consistent and artists can tune art up for it.

For some game series (say Hyperdimension Neptunia) fan art captures the essence of art in the game but for the big Nintendo games on the 3DS (say Fire Emblem Fates) fan art doesn't look like the game art at all because the game art is calibrated to the characteristics of the display in every way.
