Lacie tech response was as follows: "The monitors shouldn't "wear

what of a difference. If I am interpreting this correctly you are
asking if you can make the monitor star to fail with setting such as the
ones you are using. The answer is no. The monitors were designed for
all the setting they are capable of. However on day just like any other
device the monitor will fail due to age, defect, or abuse."
What LaCie tech support isn't telling you is that, long before the
monitor reaches the point of death, it will reach a point where it's
unable to attain the requested brightness in the calibration.
Phosphors -- the compounds that actually emit the light -- do indeed wear out.
You'll probably be able to calibrate the monitor to 100cd/m2 for
about a year, after which it simply won't be able to attain that
luminance level anymore. I have a 14-year-old Apple 13" RGB monitor.
It still works, but it can no longer achieve anything that really
looks like a true white, or, for that matter, a true black. It hasn't
stopped working, but for the purposes of calibration, it wore out a
long time ago.
I usually aim for a luminance level of 85 cd/m2. A monitor should be
able to hold that level for 3-5 years. Barco recommends a
conservative 75cd/m2, and aims for that in their default calibrations.
If you want your monitor to last as a viable calibrated display, I
strongly recommend you lower your luminance aim point from 100 down
to something around 85.
