I will have to agree with this. Back in the 90's pretty much everyone had Angela Bassett fancast as her. So to see her cast as Black Panther's mom (fans knowing someday her son will marry Storm) was just almost magic. Personally, I just get annoyed seeing her film versions with light-pigment.
At this point I want Naomie Harris to play her. However, we may not be seeing that iteration of the X-Men for another ten years. I might suggest two things in light of this discussion.
1. Has anyone noticed that the superheroines were mainly non-"white". Talk about diverse.
2. This could've played into the backlash of Captain Marvel a few years ago. Even though the movie (for me) was one of my least favorites in the MCU.
It turns out that, while the CGI for Stillwater is done by Polygon Pictures, the 2D stories told by Stillwater are animated by Studio Fost, who did post production for Wolfwalkers, and have done other works for Cartoon Saloon.
