The spy first came out SS 05.
Yes, the texture was not nearly as pronounced in the first batch of bags, and the color and finish of the leather is different on the cognacs as well. Because there was so much demand for "texture, turtley" bags, Fendi changed it's production to produce leather that was more textured. Also because original SS 05-FW 05 cognacs didn't have a shiny protective coating, the dye with wear unevely on the bag (especially where the front flap rubs against the front of the bag, and the corners). Some SA's claimed that this was an intentional effect, to make the bag's leather more vintage-y. However, again, angry consumers returned their bags, demanding higher quality and starting in SS 06, the cognac spys had a shiny protective coating added. It doesn't make the leather less soft, but it does darkened the leather slightly and make it less prone to wear.
