Could be a ‘smug’ expression, smirk, or a type of grimace.
Might be a wide, closed-mouth smile. Really depends on the reason behind it you know?

“Shit-eating grin,” tbh
Not totally a facetious answer. It’s definitely subjective and assigning a value judgement, but this is a real term that I and others might assign to this kind of weird, smug-seeming smile in this context.
(Maybe not exactly a grin, actually, because I think those are supposed to be toothy?)

The closest single word is "smirk" but I would describe it personally as an infuriatingly smug, shit-eating grin
