I bring up the natural lighting environment, because the top of the line OLED tv's aren't as bright as LCD displays backlit with LED's. The latest OLED's are brighter than before and can do infinite contrast because of true black, but technically aren't as bright as the premium LCD displays. This might possibly cause issues in very bright rooms.
Only one manufacturer (LG) makes OLED displays, but both Sony and Panasonic transitioned to OLED on their top of the line TV's. So in reality, a Sony or Panasonic OLED TV is an LG manufactured display. Samsung is pushing their separate technology called QLED, but true quantum dot displays are actually experimental. Samsung does make some great TV's too, but it's still essentially and LCD tv.
If you want to be blown away find a Best Buy that has the LG W7 model. It's .15 inches deep.
