This sparkling gem is in the middle of the article--praising the care and authenticity of the depiction of Native Americans.

And here's the article's opening paragraph describing the same dedication to authenticity in depicting the Utah citizens:

"Howard Berger, the head of makeup on “American Primeval,” a Netflix limited series, thought he had achieved the optimal level of grime. He prepared a makeup test — muddied necks, blackened fingernails, dirt painted inside an actor’s ears — and showed it to Peter Berg, the series’s director.

Berg was unsatisfied. “‘More! More!’” Berger recalled him saying. “‘Come on, man. Cover him in dirt, like he hasn’t bathed in a year.’”

Berger did. “We went ahead and just kept making it more and more grungy,” Berger said."

There seems to be two different rules applied. The production crew seems committed to righting the legitimate wrongs from generations of previous Cowboy and Indian movies by inverting the ugly stereotypes. That's understandable but it's not "authentic."

Two more quotes from the director:

“It’s important that we represent the world as it truly was — good, bad, indifferent, ugly,” he said. “Once you cheat that, it doesn’t land the same.”

“He wanted it dark,” Stateman said. “So we eliminated all birds. There are no birds in ‘American Primeval.’”
