Apparently unpopular opinion (?!):
Having a BAME actress portray Ciri (or any other character) in Netflix's adaptation of #theWitcher would not detract from the quality of the story at all, but actually stands to add to it.
I'd personally love to see a BAME Yennefer.
You could also argue that it would be beneficial for communicating the variety of different nations comprised within that world. Adaption never needs to be complete or strict.
