Of course you notice. I never said you wont notice. But the nice feeling dies down very quick once you get used to it (which you will extremely fast) and then only when you go back to lower hz you will notice it again. So it practically makes no difference. Even more when the only real purpose is for something as static as scrolling. 120hz won‘t improve your scrolling or add any new features. It‘s literally the same. What an absolutely laughable use case for high fps displays. And on top you get a worse battery life as well because the display drains more power.
