Since light and matter exist on a quantum level, all photography is digital. Light and matter exist on a macro-scale as well, so it's also all analog.
So how do express the difference, theory-wise, in analog saturation vs digital clipping? There is a distinct physical aspect going on there - and perhaps if sensor sampling is the ultimate limiter, then yes, CMOS/CCDs are similar, but if they themselves are the limiter, then no, it's not the same thing - regardless of the fact that we're all made up of atoms.
