Quite Wikipedia: http://en.wikipedia.org/wiki/Color_difference

"a ΔE of under 1.0 is supposed to be indistinguishable unless the 
samples are adjacent to one another."

Note the "unless the samples are adjacent to one another".

E.g. for medical display systems it is (in Germany) a requirement for 
the monitor to be able to separate even the top rows and (believe it or 
not) there are people who do see the difference without any problems.


But did you even care to read my post?
Where did I say that it is expected that you see the different boxes in 
the *top* row?
Do you think it is a good idea to confuse people while I'm trying to be 
helpful?
Are those rhetorical questions?
