I definitely have a couple pieces of original verde that came from different lots or they changed the pattern slightly while in production - some look more "crisp" and the tan is lighter in them while the others look more "dingy" and the tan is darker, more of a brown. Maybe the same thing is going on with the verde 2.0 pieces you're looking at?
Cameras and lighting can also play a big part as mentioned. It's also not all that uncommon for textile products to vary slightly from one run to the next, or from fabric to fabric, usually it's not as pronounced though.
