I got a reply back from the guy who posted the video and he did say that the pulsating is not visible in person, just a result of the camera frame rate vs refresh rate of the display.
You could perhaps include an option to disable the effect for true to life accuracy but I personally would leave the effect on as it looks great. I guess you could also try increasing the pulse frequency to a faster speed and that may still provide just enough flicker to be barely detectable to the eye but more true to life?
