Light (white) spots on my MacBook Pro (15-inch, 2016) with TouchBar
This occured on my laptop's LCD in recent days. It's not a dead pixel and not a pressure mark either (I always carry my MBP in soft sleeve and never had an incident with it). It seems to be a factory's fault not the user's.
After some research, it seems that the problem is with the LCD glued badly. I think LCD detaches from the inside and causes more light to pass through, making that spot brighter. If you check closely the image on that spot is being displayed still, just brighter than the rest of the screen. Some people suggested to take a cloth and gently wipe that spot while pushing to fix the problem. I tried it on mine and nothing worked. My warranty is unfortunately expired and I do not have Apple Care either.
