I thought one the main premises was that each sensor would absorb all
the light for a certain range of wavelenghts, and not at all respond
light outside that range, so that it would continue without any loss of

that there weren't filters as such, just differences in the way the
photo diodes respond to light, or whatever.
But maybe the problem is that it's not quite like that in the real world...
Quite possible that that is how they implement the layering, by
embedding the light-absorbing dye into the photosite chemistry, but
there's still absorption between the layers which causes less total
light energy to strike the third layer than the first.
Yeah, there is bound to be some loss. Still, we're comparing with a
setup where you quite deliberately block out a large proportion on of
the light at every site, though, so there should be quite a bit to go on..
