It has been my experience that S&W 6XX series stainless steel revolvers don't come "polished" from the factory. All of mine came looking pretty much the same as the OP's.
I polished my 686 up, and it looked pretty good. It's pretty easy to polish the tiny scratches out of stainless. But, after two range trips, it was right back to how it was. I didn't want to take felt pads and museum gloves to the range, so I gave up on polishing.
My Kimber KS6 did look good out of the box, the box was still sealed when I purchased it. After shooting it a few times, it looks like the 686.
Teddydog; My comments are not meant to be holier than thou, it's just the nature of things, guns get those tiny micro scratches, and they show up on stainless steel.
An hour or two with a good polish, followed by some museum wax will make your revolver look super. Be sure to take some pictures, because you may not feel like polishing it every couple of range trips.
Shoot it, and enjoy it. It will polish back up any time you get the hankerin'.
