I know the difference, but when I am at home watching content, I seldom think to myself "Oh wow, this looks so much better!" It's mostly "Huh, looks the same as yesterday." Sure, it looks amazing when I play Forbidden West, but most people get confused, including me, with this QLED versus the mini-LED craze Samsung calls Crystal UHD, etc. LEDs are still hyper expensive, and so they are skirting the law with naming.
A QLED is not exactly an OLED, which is not a Mini-LED, or a LCD? Most people see "Pretty Colors" and would not be able to tell the difference between whichever technology is being used. They see "TV Look Better, I'll buy the cheapest or biggest one!"
VR/AR is a gaming toy, that no one has given me a single application beyond minute applications in an extremely educated setting such as Surgeon or Architect, I would say the application or use case is just as minute as is the market.
What can it do that isn't already being done on a smartphone, tablet, or TV?
