It will make a table with cells whose text is just slightly off of the background. You can stare are them and explore the limits of your visual system and your computer's display. (No one will be able to see all of the text on any statically adjusted display.)
Additionally, on this MacBook Pro I looked at a greyscale gradient which I have used over the past and decided it was poorly distributed, so I ran through the color calibration (expert mode) in the Displays preferences pane. I ended up with a much better distributed gradient, but I introduced hue distortion so I didn't keep it. But there seems to be room for an improved profile.
