Honestly, I think it has more to do with the gutting of Pixar and Disney studios after Lassiter was forced out. I believe I heard that that Encanto was the last Lassiter idea that he pitched to Lin Miranda before he left. I think that probably helps explain why it seems cohesive. Versus almost all of the more recent Disney and Pixar stuff feels like poor copies or overly targeted identity flicks. Disney studios is kind of a mess, almost all of the innovation is now happening outside of Disney. Lego movie, spider verse, etc.
