I've used A LOT of TV's. Backlight bleed is EXTREMELY rare, people confuse it with clouding/glow/flashlighting. Bleed is when you see light under the bezel, because it's defective or not attached properly. It's not important to know the difference, defect is a defect, but an incredible amount of people get it wrong.
Now as far as my experience with TV's, despite 2x-3x-4x-5x-6x sizes of these 'gaming' monitors, they generally have less defects than these monitors. They're among the worst I've seen as far as defect ratio is concerned, and I bet you that they're cutting corners to lower cost.
