in the case of FF vs m4/3's that will be 4 times more light at equal apertures. That translates into better colour depth and hence the appearance of a richer, smoother look.

Ok so help me understand this thing with BOB. You just said exactly what i picture in my head. FF will receive 4x more light than a MFT at equal F stops and equal SS, because at equal F stops the aperture itself isn't really equal. How on earth, with a 4x light advantage, can they get the same SS unless the gain is different? If they are both at ISO 200, both at F2, both at 1/100 SS, and the FF has 2 stops less noise, doesn't it have to be because the gain on the FF was less than the other one? How else would the smaller sensor get those two stops of SS back?

It's a good question and I'd like to know the answer as well

What's being 'got back'? Think about it. Somewhere there is an implicit assumption being made that is takes so much light to make an image and if you reduce the exposure that has to be 'got back' with gain. It just isn't the case - the amount of light needed to make an image is arbitrary in the first case.
