I can not look at the english page for it anymore, because of Google's automatic forwarding rules. Maybe they changed the marketing by now? I'm pretty sure it was marketed for all skin colors, not just darker skin. And the talk about talking diverse photographs was the first "marketing section" after the tech specs. Yeah they also announced they have a "tensor processor" now. I don't think that was/is an actual selling point.
I didn't reger to the video ad, but to their web site. I'm saying their main selling point was (and is) that the camera does well with different skin tones.
The selling point is it's better for darker skin. Not just diverse group photos.
