WotC has had a profoundly bad track record in this regard both historically and within recent memory. The 3rd edition thing where Eilistraee died to 'redeem' her drow followers by lightening their skin color springs to mind.
To be fair to Wizards, I'm fairly confident that that whole thing wasn't actually within the source book lore of any edition at all - quite the opposite, in that Eilistraee is all about drow acceptance and empowering drow as they are, and encouraging them to forge a true identity that brings together and promotes unity, *As Drow*; that there is nothing wrong with looking the way they do, and would generally find the idea of forcefully changing them into something else, under the idea that somehow what they are is 'bad' to be an abhorrent concept.
The whole deal with drow 'redemption', and with drow being 'purified' of their dark skin by Eilistraee's salvation, was solely the province of the War of the Spider Queen books, which is a series that Wizards likes to try and pretend was never published - especially since it specifically disregards and flies in the face of so much of the other surrounding and related lore both past, present and future of it, and instead shoe-horned entities (such as Eilistraee) into complete nonsense that ran against their established descriptions and character, just to fit their rather gross and disgusting narrative in regards to race. No 2e, 3e 4e or 5e source book makes any mention of this kind of 'redemption' or 'purification', nor of 'evil-red-eyed-drow' Vs. 'good-blue-eyed-drow', at all, and the book series in question has, for all lore purposes, been entirely overridden and disowned by Wizards.
I don't know what it is with this obsession with changing drow's physical appearance, because it inevitably ends up making things incredibly uncomfortable because nobody seemingly thought about it for more than 5 minutes. Drow redemption being signified by changes in physical appearance is something I hope doesn't make the final cut. Like if we reach Baldur's Gate and run into some Eilistraeens and they're all violet-eyed I'll be cross.
Unfortunately, the way that Larian handles race, racism and differences between peoples, in their other games, leaves me with the distinct icky impression that they follow the same kinds of gross mentalities that the authors of WotSQ did, and worse in some cases... so there is a strong possibility that that is exactly what we can all expect to find, and there is very likely to be nothing we can do about it. If the race-related tone and language continues to be handled this way, as it already IS in BG3 so far, it may even lead me to give up on the game as a whole, just for being too unpleasant to sit through (Mechanically, I Wanted, very much, to play through D:OS2 a second time, to do other things... but I simply couldn't bear the background radiation of extreme racism that pervaded every story element, and, more importantly, being forced as a character to go along with it, accept it and treat it as normal and okay, without objection; I couldn't stomach a second play through, for that reason).
