Yes, the ethnicities were reflected accurately, in my opinion. Excellent museum... my favorite of all the Smithsonian's in the DC area!
I spent several hours there, and don't recall any mention of, or even the presence of... brown colored people. There were some pictures of them, as it related to Hitler's objective ..... as to WHY... I would refer you to the organizers, and/or, management. Overall, though, the museum was very sad, and awakening..... I would highly recommend it. It is all... FREE.
Yes it has all forms of life and humanity. It's very inspirational
