I suspect it's hard for us to imagine the consequences of fame at such an early age, and especially in such a highly-charged role as Sciamma's Marie, where everyone will tend to assume that you are playing yourself. Hollywood is littered with victims, most recently Edward Furlong from Terminator 2.
Although thankfully the French film industry doesn't seem to be quite so destructive as the US/UK's, or to routinely require surgical alterations to its female leads, I wouldn't be at all surprised if Pop'slabellefolle hadn't had a flood of cheesy offers after NdP, most or even all with 'the fantasy of cotton underwear' high on their agenda.
However that may be, and whatever privacy measures may have been found necessary, l'Acquart and her agency have since pursued a quiet, steady course that looks well designed to give a thorough grounding in all aspects of her craft [and sullen art] - feature films, TV, short films, at least one ad, and now theatre/mime with Snow White - and, as Sciamma meaningfully said just after NdP,
'she is only interested in quality projects'. Acquart is very good at silent expressiveness, so I'm sure she is even now slaying them by the houseful in Snow White; but us poor aliens are just going to have to wait for the next NdP-scale international feature film, I think.
