CIE2000 is for when you want to "feel good" about the errors you can't fix.

There isn't a whole lot of difference between DE76, DE94 or CIE2000 near the neutral axis - most of the tweaks are in the saturated colors which tend to be de-weighted in DE94 and CIE2000.

All I'm saying is that little "errors" add up in a Y/Cr/Cb color system ... if your "zero" is really something like "0.1," that just makes it harder to find all the other colors. So be as ruthless as possible when you can.
