Sony TV Discoloration

I have a Sony LED TV that has developed a discoloration in the upper right corner. It only happens when the picture is darker. It doesn't do it when the color is lighter.

I have attached a photo of what I'm talking about.

Has that part of the screen been subjected to a lot of sunlight or Windex?

Has it been hit by say a fist or a chair back or a ball?

All I can think of is some kind of physical damage or maybe just biodegradation of the edge allowing air to seep in between the layers of the screen, in turn resulting in corrosion not much different from corrosion under the paint on a car body or tarnishing of the silver layer at the edge of a CD or DVD..
