After Disney bought Pixar back in 2006, movies that are now considered to belong to Disney started carrying very Pixar-like features that are usually quite different from what we're used to seeing in Disney movies. For example, Pixar usually tends to design their characters to be caricatured. Even though the adorable Carl's character from the movie Up wasn't really supposed to be a caricature, it still has some features that clearly belong to the Pixar tradition; such as a nose shaped like a balloon and a not proportional head that is definitely not natural-looking, and definitely not something we are used to seeing in Disney movies.
