I don't have the Cape Cod Blue Sport, but here's a pic of the Leather Loop in that color. I tried on the sport and the effect on the SBSS watch is almost the same. This pic is lit from the window behind me, so the blue looks it's brightest. I think it looks a bit more subdued most of the time. Hope it helps.
BTW I really liked the sport loop on my watch. Just ended up with this one. Good luck!
