Even if they did, the new rules state that you can create a character of any skin color, sexual orientation, and gender identity. We had asian and black people in BG and NWN. Also, Star Wars has gay characters in comics and black and latino people in films (as leads even). So your point is moot, because even in those universes, Bioware could do a diverse cast. In the Witcher universe, there's hardly any minorities.
In DnD universe you always can find everything close enought and could create any bizzarre and halfthat-halfthat creature and play it if game master agree. the other question would be how the hell he is there and how become a hero in this story...DnD almost does not care a bit about explanation and reaction of who you are and others
this is new disney canon of star wars, and bio with makeb add some of them, before in the whole starwars there was only straight relationship for childmaking and a hutts hermaphrodites and insectoid race with many genders as "minorities"...about pigmentation(let be clear that there is no "whites" "asians" and "blacks" "latinos" in star wars) there is so many different races in starwars especially humanlike that noone care and they are like twileks everywere almost on each planets with millions peoples who migrate and migrate and migrates everytime they wanted, thats not the same as with many universes and it always was since first starwars films and books. comics
Witcher universe in dark medieval setting have a very rare amount bisexuals-lesbians if you are about this minorites who mostly only a old mages males and females and Ciri as a main hero, "dark skinned asians" exist there but they far far away and we see few of them in books and kinda many(if we can understand simple truth that lands where we have game story are far far away from those there they can be seen commonly) in Witcher games
the problem is when you create some char or add anything(like elephants and zebra in show wasteland) you kinda need his history and explanation, this is senseles and less realistic to add everything, and this ruins game universe
in DAI as i can see and what makes author of this tread confused and talk about political correction, that there is a problem with to many "rivanies" in the ferelden and orlais lands there they are no common but for some reason and this is not explanated they are in DAi even that 10 years ago in DAO they were not at least in ferelden, i am not talk about Vivienne who have full explanation of how and where, i ma talk about others like Denet mother Giselle and others
about non-straits peoples this is Orlais lands and they as Antivans always was stated to have much into this sinse the beginning of DA, stil this is strange to not give any reaction for such things from non-orlesians like there was in DAO and Zevran have talk about such and we have Ogren reaction and others, in DAI only Mother Giselle have something very small and mostly about tevinter mage stuff
Qun(i am not consider Bull words as truth since Sten and lore was said how it worked). Tevinter must be another story there such relationships were not tolerated much and this would be silly to show racism and nazionalistic, religion. magictolerance stuff of Thedas nations cultute but not other sides...Dorian story already are kind of stupid and all that whine not make sense if noone was really care about who he was and with who he do romance as with Crem would be about a woman who was go to army and pretended, lie that she is a male until it was discovered
Many characters were really not suited to be together, to be as Inquisition companions and Inquisitor always have his herald and orlais chantry stuff no matter what and who we are, even after we know the truth about elven powers
