I'm going to assume that because the copy just says "skin tones" and doesn't specifically call out darker skin the gp (or whatever the first commenter is) is confused by what they're seeing and reading.
I did a bit of searching just now and found that Google is calling this update "Real Tone." https://store.google.com/intl/en/discover/realtone/
From what I can tell, they have likely improved things for people of all skin colors, but probably moreso for those with darker skin due to increased focus on ML training. They include a person with fairly light skin on that page in comparison to the product page.
The copy on the page itself seems to disagree with you
> Portraits on Pixel represent the nuances of different skin tones for *all people* beautifully and authentically.
(Emphasis mine)
There does seem to be a discrepancy between the copy saying "all people" and the photos above that paragraph only including individuals with darker skin.
Edit: I'm acknowledging that there are photos of white males elsewhere on the page, but I think my comment's parent is specifically talking about that one section?
Aside from that, you can also infer from the negative view that the copy is implying that other phones do not represent the nuances of all people, which is the reason that they said it to begin with.
But you knew that already, didn’t you?
