As long as the LCD display still can hit the desired target luminance and
has some brightness left to spare, and as long as it doesn't exhibit obvious
unevenness or color drifts across the viewing area, then I would consider
myself lucky and keep it.
I've had my G4 PowerMac and its Apple Studio Display since 2002. The display
is still working well, looks reasonably even across its surface (when I look
at a full-screen white page in Photoshop), and has a good eighth or so of
brightness left to spare at its current luminance of 155 cd/m2. I may have
been lucky, but this unit still appears to have plenty of life in it, a full
5 years into its life.
There have been quality issues with Apple Cinema Displays (which came after
the Apple Studio Displays), but my sense is that Apple Studio Displays were
solidly built.
My advice is: make a profile for your monitor, see if you can hit your
target luminance (and still have some brightness left to spare), and check
for any unevenness across the viewing area. If the displays passes these
simple tests, then it's still got some useful life in it, in my opinion.
