Manufacturing defect on retina display by Apple

I’m disappointed with Apple. My Retina monitor of an almost 4k $ Laptop is now looking really ugly. The reason is a manufacturing defect by Apple, the anti-reflection coating has started a degradation process that can not be repaired if not by replacing the whole display. The cost for replace the display is almost about 1K$. Unfortunately on my MacBook Pro this degradation process has started 6 month too late for a free replacement. But I never received a mail from Apple advising me about this possible issue on my MacBook Pro and now Apple won’t pay for his manufacturing defect.

This is not a serious behavior of Apple against those who pay thousands of dollars for its products.
