In the short I shard Martin says its filmed in Morocco. They could have filmed the Yunkai scenes in a few locations tho.

Found the short

Theres some interview with RR Martin where he was asked about this scene in the show and he drops a gotcha along the lines of “well in the book theyre never described as being black, it was just a coincidence because we filmed in a country where the extras we hired were all black”

Its posted on youtube somewhere as a “RR Martin owns the libs” kind of thing
