ELI5:Why is nudity of "modern" people censored on the Tv but nudity of "primitive" people isn't censored?

Why is nudity of "modern" people censored on the various reality tv shows but nudity of "primitive" people living in the jungle isn't censored?

When Bear Grylls went swimming naked in the river on his survival Tv show they censored his buttocks or when women go topless in shows like Big Brother they censor their breast or air that episode late at night but when they show native people living in the  Amazon rainforest they don't censor their buttocks, breasts and genitals.  

Isn't this a double standard or even racist?

Legally, in the United States, the thing that is regulated is not the appearance of a nipple or butt cheek. It's "obscenity." The idea is that a boob or a butt presented for the purpose of titillation or in the context of sex is different than the same body part presented as part of a presentation on anthropology or science. 

As a result, TV stations are usually willing to risk the Amazon stuff for the sake of accuracy. They usually aren't willing to make the argument that Big Brother nudity is about anything more than sex, and so they blur it. Bear Grylls would seem to fall somewhere in between, and they may blur that more because of something in his contract than something like this.
