I just received this same model case, in black. It appears smoother than what I see in your photos, very little pebbling even under close examination, at least on the large flat area. I like it, hopefully it comes into its prime nicely like the Apple case did on my plain 12 (made the big jump).
The camera control cutout works for me, the pad of my index finger fits down into it just fine.
My only big negative so far is that the fit is SUPER tight. I mean, I checked the label on the box to make sure I received the correct item when I went to insert the phone. I've only removed it once, and it was a chore to get it off, I seriously feared something was going to happen to the phone by pressing on the lens area so hard. It did go back on a little easier though, so I'm sure it will loosen up a bit over time.
A couple of minor nits are that the action button is slightly skewed, not quite inline with the other buttons, and that the cable and audio cutouts don't quite line up with the ports on the phone (as if the phone wasn't quite pressed all the way down into the case). 8.5/10
