i mean, lifespan of the monitor will be reduced? if yes, how much?
There should be none.
Many LightBoost monitors, such as the ASUS VG278H, don't use any any boost voltage at all.
Even when a moderate boost voltage is used (for brighter strobes), the rest period between strobes compensates for that. The oldest LightBoost monitors, that uses minor boost voltage (e.g. XL2411T or VG278H), haven't had any reports of brightness degradation after a year of 24/7 use.
LED's actually last longer when they're strobed (at original voltage, at least). LED's don't perceptably wear out when cycled, they can flash millions of times per second in optical fibers (transmitting binary 1's and 0's by flashing an LED ON/OFF many times a second. That's what your Toslink optical connector on your Yamaha/Denon Surround Sound Receiver does!) LightBoost is a designed feature of a monitor, used for NVIDIA 3DVision to brighten the screen when used with shutter glasses, but LightBoost became more popular during 2013 as a method of motion blur elimination.
Generally, the average brightness is a more accurate indicator of the wear-and-tear on your LED's.
Most monitors are darker in LightBoost mode, than in non-LightBoost.
