it very well could be, they're extremely hard to photograph in a manner that can show the difference between a normal and a satin finish.
@VickySilver was most kind in sending me some images of satin ones, but he agreed too that the images didn't do the finish any justice.
I have a couple more of these coming (10million to 1 against) that they aren't satin, but I only bought them to try to get a good overview of the range of finishes these things can display, to try to create a good reference point of what isn't a satin finish. Obviously I'd love to stumble across one for a quid, but as yet I ain't that lucky
I should be able to get a decent set of "not" images up next week.
