iOS 7 Dynamic Wallpapers

Hello,

I have iOS 7 installed on my iPod touch. When I go to the dynamic wallpapers page, only some of all the dynamic wallpapers are there. I do not have the green one, but have the original blue to purple, gray, yellow, red, and blue. I really like the green dynamic wallpaper, and is really the reason I downloaded iOS 7 (I think the menus and other stuff is way to white). Is this just a bug, or is apple expressing its dislike for iPod Touch users?
