This is on a MacBook Pro set at 6500K and 2.2G.  I can't comment on  
the a & b values; they seem to be close to yours.  However, your L  
values seems to be very low, especially for the Eizo.

Shouldn't pure white be a=b=0?  < 5 seems like it ought to be okay,  
but 20 seems to be pretty high.

I normally run at 5400K because it matched my printer better.  On  
that I got:
L=103.955
a=-1.910
b=-6.921
and
K=5473

For other temperatures, a seems to stay around -2, but b grows:
   -2 @ 5400
-13 @ 5800
-18 @ 6200
-21 @ 6500
I have no idea what that means, if anything.
