I think it's less notable than the media is making it out to be. In 2016, Trump was an unknown quantity to minorities. It was presumed that as a conservative xenophobe with racially charged rhetoric he was a monstrous individual, and people voted on that mere presumption. In 2020 the majority people of color still believed that he was unsuitable, and hence voted accordingly. But people's lives are not monolithic. Some minorities, regardless of group, prospered on a personal level over the past 4 years. They did better, their families did better, they were not dissatisfied with their lives under Trump. For some of those people, that personal reality took priority over what some call "tribal" politics. So they voted for more of the same.
It's for basically that reason that incumbent politicians are usually favored to win. As long as people's lives go generally okay, they want to stick with the devil they know.

Really? From my perspective, the media has not noted it at all. I had to notice it in a Twitter stream before it disappeared down my feed forever, to know these statistics. It seems more notable than zero, and therefore to me more notable than the media is making it out to be.
I don't disagree with the rest of your comment. Peoples' lives were determined to be better under Trump, so they voted to keep it. Privileged people with the benefit of discounting quality of life bumps that were significant to others but insignificant to themselves, were more likely to vote based on appearances.
