I can see that 1 is "off". 2 and 3 look close but 3 is a little darker. Is that what you are seeing? Can you explain with 3 over 2?
--- The idea of this image is to show how much light is lost correct? So white is lost light and red is reflected light, right?

Here is a good reference chart on IS images

http://www.ideal-scope.com/using_reference_chart.asp

3 has a nice even red through the middle of the image, while 2 shows some leakage (the paler red under the table), comparable to the "very good" in the reference chart.

EDT: Also 2 shows greater leakage and greater painting around the girdle
