Actually the point I was making is quite simple.  Unless the pixel has 
been adjusted to appear correct in that display space, or very 
carefully converted to that display space so it appears correct, then 
it can be any random value at all.  As others have pointed out, 
multiple transformations are not usually a perfect "round trip" so it 
is best to do all the work with the master image in one colorspace.
