Papyrus doesn't have white pupils, he doesn't have pupils at all. There is the one anime style Sprite with his eyes sparkling, but that doesn't count. Also, it's interesting to note that ASRIEL only has white pupils in his GOD forms. I personally believe that that is only because of the fact that kid ASRIEL has a smaller face, but it might mean something. IMO, they just have white pupils to look cool, like Undying, but I suppose Undertale is deeper than that.
