I have an iPhone 6 which once had a third-party screen installed to replace a cracked one. The replacement screen looked great at first - indistinguishable from the original one. But over time it has developed exactly the same issue: a yellow band/border/ring around the outside of the screen. I wonder if this is a wider issue within the LCD industry, rather than just being specific to Tesla.
