No, she has that quality about her as opposed to Raquel whose smiling cause she's a "face" and mean mugging when she's a "heel" It looks natural when Rhea does it no matter if she's face/heel(Her current heel run with The Judgement Day and her few months back face run with now WWE smackdown women's champion Liv Morgan)
Sure, it served it's purpose for "one match on the card where guys wrestle" imo, at times you could tell Gable was carrying him (I know the heel carries the match, but Gargano seemed a step slow)
