Wow, I think that qualifies as "over-thinking" the situation. ;-)

Our research has shown that at least 99% of LCD displays that offer a  
contrast control, cannot actually control what "contrast" controlled  
in a CRT; that it to say you can't adjust white level using that  
control. So we stopped offering that step for LCDs in more recent  
builds, since it was not accomplishing our goal, and was one more hoop  
for people to jump through. Besides, in attempting to adjust white  
levels with the 'mock contrast control' on LCDs, it was possible to  
leave the display in a less optimal state in other ways.

The more global situation here is that old-time CRT users still want  
to be able to adjust the timing and and set the point gap, oops, I  
mean adjust the RGB Gains and set the White Level, and are frustrated  
that LCD calibration is less about calibration and more about  
profiling, since there is so much less for them to do under the hood,  
so to speak.

I would suggest you "reupgrade" when you have the time.
