The orange cover does (you can try this yourself, save the image from my blog and then crop it to the different colors, and superimpose it over the same search terms).
For Ebooks this is all that really matters. The cover AS A THUMBNAIL must look:
1) DIFFERENT enough to stick out and draw the eye.
2) INTRESTING enough to cause the shopper to look to learn more.
IMO nothing else about the cover really matters. The hard part is doing that.
In Ebook land, the full size cover is almost completely impact-less, only the thumbnail matters. IMO
