Yeah, but as I said, every display has some of it, even ultra fast gaming displays, it just how LCD/OLED works with todays technology. So we know there has to be some there, if it is enough for you to see it in real life or not is what we don't know. Different people will notice different levels of the effect, and watchinga video on it is not the same thing as seeing it live.
If you really want to find it, running the display scan skew test can help you in doing so (that's what I had to do). But it is good to know that if you do find it you will most likely be bothered by it.
