Not sure that it means anything, but about the colours:
Looking at the images in the linked page, I see those as pretty much the same as in Mike's photos, bearing in mind the different background colours (as well as the lighting used) could have an influence on the actual shades of green.
But when I click the linked page initial images to get the enlarged views, they all appear a much darker (or "richer") green. But perhaps that is due to the enlarged versions having a touch more contrast than the "thumbnails".
