I'm not arguing that it's perfect. In fact, on the back top left corner I have a small scrape on the top edge of the band. Same on the top right and bottom left on the back. That's from having it in my pocket when working on my car outside. It slipped out and dropped to the concrete. I kicked myself for that because there was actually no need for me to have the phone out there with me. But a Sharpie took care of the top right corner, although you can feel the roughness of the edge with your finger.
There are other small knicks and whatnot but all of this is in the bezel area where the metal meets the glass. It's not like a scrape along the side or back or anything like that. I consider this (outside of my idiot droping of the phone I mentioned) to be normal wear. I have to look at the edges with light behind me to see this stuff.
So, if by silver dots you mean what I just mentioned, then yes. As far as the pics, those were taken with the crap camera on my 3GS. My HTC Touch Pro has a much better camera and I should have used that but it's harder to get pics off of it.
Anyway, here's a different set from back in April that was taken with my other phone. Not much has changed.
