This is an interesting question. I'd put this profile personally at 8/10 on the "woman" confidence scale. She looks quite womanly.
I do feel that Brazilian escorts in general have more masculine features.
Where that stems from, not sure, but if I have to enumerate, it might be in order of significance:
1. Broad jawbone
2. Large body frame
3. Virtually gauranteed body enhancement (butt, boobs, lips)
4. Excessive make-up (questioning if they're hiding facial givaway-signs?)
I have no clue on what subset "post-op trans" make up in the "women".
Then again, if I've fucked a pussy, sucked some tits, and deposited my load. Into what looked and felt like a woman ... and I come away with that narrative, is that then my reality? Perhaps so, until somebody else challenges it ...
Very bizarre space ... my general position is to go for the very feminine looking Brazilians. Having said that, there's no reason why those won't be post-op trans ...
Sorry, just rambling, perhaps I've diluted your original question.
