Here is the reply that I received from Eric Liu:
The surface of a worn cam lobe would
generally have a much darker hue than one with very little wear. If you
look closely at the picture of the failing cam, you will notice that the
color at the edge of the cam lobe is lighter than the rest of the surface.
This is because the width of the cam lobe is wider than the rocker arm pad
in the Nissan KA24E engine; the edge of the cam lobe does not make contact
with the rocker arm pad and is thus unworn.
The wear patterns on the surface of the passing cam lobe is merely light
scuffing. It looks more severe than the actual failing cam lobe, because it
lacks color uniformity.

Your initial reaction mirrored the one most on here had when buster first posted the pictures on this board.
