Sometimes it shows up in smaller area's, but it's more of a rippled shading effect rather than a distinct color changing pattern. If you look at shading at the tops of the two pictures it's almost more a sinusoidal pattern. The finer fingerprint on the right side of the green background is a camera artifact.

You are describing exactly the kind of effects expected due to the CRT and not the signal circuits, so, case closed.
