Yup I more or less agree with that. White male is basically the default, in a few cases developers are now saying "well ... hey, maybe the character can look at little different". And that's fine too, that's just a developer realizing that the audience their making games for isn't a one dimensional demographic.
The thing is most developers care more about their characters from a perspective of theme and narrative than they do genitalia, which leads them to starting with the basics and going from there. There is rarely ever a reason to highlight race or sex in a video game, so in reality choosing a white male as the default is actually stearing away from those conversations. Which I think is usually good, i'd rather just focus on the character.
