Did you see the updated image. I think that 4 or 5 stops will show some amount of banding, but not enough to make much of a difference. Its when you have maybe 7-10 stops where you should notice a massive difference. If the whole theory that is being bandied about were true, i.e that the multiplication takes place post A/D convertor, then how many bits does that A/D convertor have? It would have to have quite a bit more than the stated 14 bits, that way they can multiply at will and have plenty of room for the dark regions to come out.
