I just got a few packs of this deck and cracked one open. I didn't realize it from the photos, but they're not simply printed in shades of gray. The background around the "Bicycle" logo on the tuck box and the clothing details on the court cards are all done in what appears to be a variant of urban digital camouflage. It's pretty nice, really.
The Joker looked a little strange, until I realized why. Until very recently, it was always a monochrome design - black on white, no shading. Then came the WalMart Rider Backs with the color Joker that some love and some hate. For this one, in keeping with the deck's gray theme, it's the color version of the Joker but with all the colors changed to gray. The "grayscale Joker" appears on both the full Joker and the guarantee Joker.
