I think the only time they change their expresion is in that scene with Nihilego.

I even saw someone theorize (As a joke) that the protagonist of Sun and Moon came from the same dimention as the Ultrabeast and that's why that's the only scene where they drop the smile.

At least the MC of Let's Go moved their face ince in a while.
