Based off Pixar's recent movies, and a quick retrospective look at their older movies, I suspect they are sticking to their current level of realism as a matter of style, and only making slight subtle tweaks and improvements. If you compare their old movies to the newer ones, primarily you notice textures and objects are sharper, clearer and more detailed, movements of characters are more natural, and faces are more lifelike.
