This seems more like a problem for the users than it is for the OS. 
While I agree with most things in your email, what response are you 
expecting from it?

It seems that displays are all over the map and since most displays 
are not calibrated, users just have to get used to it.

The banding and posterization you see on these problematic displays 
sounds like a lack of sufficient levels in the LCD drivers, which 
can't really be corrected outside of the display.  I have read that 
current laptop LCD displays have only about 6 bits of actual level 
information.  To me this is just plain broken.

Just as we have seen with TVs, vendors will tweak their displays to be 
as vibrant as possible in the store as possible, at the expense of 
accuracy.  Vibrant sells while dull and accurate does not.
