Leds often dim faster when young. Something else will most likely fail before the leds are too dim. On the other hand flickering can be more obvious if you lower brightness of a led. Brightness is usually emulated by turning the led on and off very fast.
I suspect part of it is also planned obolescence --- when the backlight is running at full brightness, its lifespan is greatly decreased. Now the aforementioned monitor is approaching 15 years of age and brightness has reached 20/100, so there's still plenty of life left in it.
