New 5K Retina Display has backlight bleeding on black screen

Just got my 5K retina display and definite backlight bleeding issues specifically in top left hand corner. Debating whether to exchange or not. I opened a case with Apple and they are having engineering look at the photo. I spent 3K and shouldn't have backlight bleeding issues. I have never had this issue on any Mac until now. Does anyone else have similar issues with their IMac Retina display?
