I don't think you need to rush to change your examples just yet. This sounds more like
development of the glial cells to compensate for the initial bad design that put the
receptors on the back side of the retina. The authors say it helps color vision during
the day without hurting night (non-color) vision too much. But many vertebrates don't
even have color vision. Are their eyes wired the other way around...No. Do they have the
same glial cell disposition? And if the color receptors were in on the front side of the
retina then they wouldn't need sequences of glial cells to guide the photons to them.
