Of course, we might be indulging in stereotypes to assume that we know what sex or race a person might be, simply by gazing upon them.
In Blade Runner 2049 the only characters I recall having their sex stated explicitly were the two offspring of Deckard and Rachael. Nobody else was specified. And even in that case, the records were an unreliable narrator. I know GD’s remark was about Beyond Good and Evil, but I think it’s still better to avoid jumping to such conclusions in any media.
