Good writeup Ray.

I think you are right about the extra gain making up for a lack.

Don't worry I am not planning on OSC. Been there done that. They are great for brighter targets but struggle with dim objects and narrowband.

The Kodak True Sense LRGB colour filter array claims 2X increase in light sensitivity so perhaps 3X is true between mono and colour. I always thought it was less but the gain factor may be what I was confusing with QE. Like high ISO on a DSLR.
