With the caveats that you also have noise and leakage around the two ends and the individual sub pixels will not all be identical in their response. Both on a single pixel and compared between pixels.

 

Are you sure that increasing exposure will necessarily introduce noise? Overexposure could give greater color discernment as long as the camera isn't programmed to convert it to white. Of course then the camera is no longer seeing the animal like a human would.

"One can therefore use many combinations of the above three settings to achieve the same exposure. [...] For example, aperture affects depth of field, shutter speed affects motion blur and ISO speed affects image noise."

It isn't necessarily converting to white, the sub pixel is maxing out you then get leakage into the other pixels and sub pixels removing your colour differences. How you get the light onto the CCD isn't really important it's how the sensors respond to light.

 

The camera is never seeing it as a human. Humans use nonlinear sensors with high and variable dynamic range, even HDR sensors cannot reproduce this.

So make a sensor with photosites that won't max out.

 

My problem is that you lose a lot of information when you humanize the image. You lose hue in the white and black ranges, and you exclude ultraviolet altogether. Bees, some birds, and some shrimp see ultraviolet wavelengths, and I speculate that, because some animals are adapted for night vision, these animals might also detect hues in our black range.

Then the sensitivity isn't enough for things with low reflectivity. Your range is not great enough for everything to have an OK exposure under the same conditions.
