That's why they also explain them. I think the only factor that comes to play here is patience, and your background (how easy you pick up on it).
Think most are overwhelmed by the amount of choice and just pick one and go "screen is a screen". And mostly get drawn in by marketing numbers like contrast ratio and refreshrates/ms latency. Things that are easily manipulated (dynamic contrast) and don't really matter for most. 8ms is still fast enough for 99% of the users. Better put the extra few bucks in getting an IPS instead of TN.
