Trying to replicate your experiment. By actual measurement, my eyes
are 22 to 24 inches from the plane of the screen, centered
horizontally and about 3/4 up from the bottom. Looking at Shashdot,
the green bars are green no matter where I scroll them to vertically.
Of course this screen is not as big as yours. The actual image
dimensions are approximately 11x14 inches, 18 inch diagonal.

With a moderate amount of applied imagination, I can believe that a
uniform light blue background looks somewhat darker at the bottom.
Maybe this (top vs. bottom) is related to the vertical placement, eyes
nearer the top for me, nearer the bottom for you.

Isn't a 24-inch flat panel considerably larger than a 20-inch CRT? My
18-inch flat panel has about the same size display as my 19-inch CRT.
Consider two moderate-sized monitors side by side.
