Yes, I get the concept of bayer sensors and RGB. I was thinking in terms of how quickly the wells reach saturation, and if that follows the intensity curve the way it should. I've always felt that the red channel in canon sensors clips a lot faster than green and blue; ie in warmer light I seem to get more of a red/pink hue than I should and under reddish light the highlughts clip pretty fast.
That would be interesting data for DxO to collect, admittedly. The problem is that it's not as simple as saying that the sensor saturates in, say, red, at a given light intensity level. The saturation level is likely to be a curve that is dependent upon light frequency.
Even so, that could be quite valuable to someone who is interested in how well a sensor records color information.
