I did some quick tests some years ago and never saw any non-linearity as long as one stays well below saturation. It is possible that recent cameras have shoulders - on the other hand, CC errors might come from optical crosstalk between channels - light diffusing inside the sensor.

For the cameras I've calibrated the raw values for the CC24 gray steps don't track, even after adjusting for flare etc.
What was the dark frame and flat field data?
