no they're not - at least not nym and obara, only tyene seems to be played by a white actress, but i figured she prob would be, since casting has no imagination

but they've def fucked up their backgrounds... obara is the daughter of oberyn and a whore from oldtown, and she's the one who wields the whip; nym's part volantine and uses secret daggers

i'm also smh at the fact that they call trystane the heir, way to erase arianne >:c
