this is an interesting though. The sensors do not record linearly. There is more data represented in highlights than in the shadows. That's why cameras with higher bit-depth resolve better in the deep shadows.

Not every charge value has to be represented by a bit. Digitization always takes a range of analogue values and lumps them together. Digitization is a measure of 'accuracy' of representation of electron charges, much like number of pixels on a screen are a measure of accuracy of representation of a real object.
