Chosen answer: He's just gained weight. It looks like he slowly started gaining more weight around 2006 or so. In "Kids in the Hall: Death Comes to Town" (2010) he's noticeably heavier than his younger days (he was on SNL 21 years ago). By the time he was in "Man Seeking Woman" he looks very similar to how he looks in "Superstore."
