The Dusty Lavender was shiny on one side... not shiny-shiny, but it had a low sheen to it. I loved the leather (very soft and thin - from Italy, it's even washable ) - the color was just a bit too dark for my Zam to use in large areas. I did use it on my chest armor, and I'll probably end up using it on the gauntlets as well - since the areas are small and heavily weathered anyway. I don't know how the other lavender compares colorwise.
If your Zam is darker anyway, it might be the way to go. I posted a pic of it someplace here (Langsuir666's thread???) and compared it to my other colors (The veil color is pretty darn close to the real one as I did do a real life comparison at FIDM with those ).
