You really can't notice this in photos over the web, but I notice (lower end?) Pinarello frames have pear-shaped top and down tubes. It seems to be more pronounced on the Galileo. I notice a lot of guys are selling off what appear to be brand-new frames on Ebay or the Classifieds here.

Seems to me the look takes getting used to. What Pinarello models use the standard round/oval top and down tubes?

Do you mean the diameter of the tubes changes? My Galileo has that.
