I did notice something that is prob. related to what you are seeing.

I have a halogen lamp next to my NeXTstation mono.  When it is off, but I
have the lamp on for a while and then shut it off, you can see where
the lamp's light was hitting the screen (it's off on one side of the monitor).
I happened to notice it one night as I turned off all the lights.  I figured
that it has to do with the phosphor in the screen retaining the light.  That
is, in the same way that the pixel goes black after the electron gun isn't
shooting at it, perhaps it's not fully "discharging" (or whatever you want to
call it).  The longer the screen is on, the whiter the black pixels become,
resulting in an overall perception of a not so bright monitor...

Just a hunch.  Can't really support it with any kinda of techo-garb...
