But because this power is only a very short burst (milliseconds) if that, there isn't enough heat generated to burn them out. Supply that amount of power constantly over a prolonged lengh of time and it could potentially damage the LCD filaments.
Just something that I learned during an electronics course.

That is theoretically correct, but it's not how it works. A phone flash has 2 modes, flash and light. One lights up to 60 percent, continuous and the other to 120 percent for 0.4 seconds.
When shooting video in the dark, the LED stays on, with no ill effects. The power is way under what is pumped through on flash.
The flashlight app uses the continuous underpower mode, otherwise it'd be dead within minutes.
