Mostly not the random NPCs, just a few of the specific ones. There's 1. Dredd (guy at the bar), 2. Maurice (his friend), 3. Ricardo (secret agent you meet after losing the lemonade demo the first time), 4. The CEO of the company for the Goodgirl Basic demo
The issue I came across having randomized NPCs be black was the fact that they require full alternative sets of animations, otherwise it would feel too weird imo. And not all the 10 actresses have scenes with black guys sadly (Autumn Falls specifically, though all the others do). So it's put me in a bit of a pickle - for the moment you won't be seeing black random NPCs.
