Yes, I see what you mean. But then the scenario is this:
Adjust contrast for B&W (which is sloppy in grey, but you don't notice)
Switch to gray
Notice sloppy contrast
Adjust contrast for gray (which is now presumably even more right in B&W)
Switch to B&W
Contrast looks good, don't adjust.
So, what I don't buy is that if you have the contrast adjusted properly in
some grayscale mode, then it will be wrong when switching back to black and
white.
As you say, having it jump back to some old value could be really
disturbing. Especially if you've had to adjust the contrast to compensate
for a temperature change.
Overall it's probably more likely that users are adjusting contrast because
of temperature changes than because it's mis-adjusted from a previous
adjustment. In which case keeping the last adjustment in any mode is the
most useful behavior.
