I would return it and ask for a unit with a serial number from a later week. The serial numbers don't indicate what display manufacture made the display but based on other threads the QC vastly improved in December weeks.
Went back later in the day and I'm convinced the display models had been refreshed. Anyway, tried again and got what seems so far to be a perfect screen from F4KL factory and a week 47. Screen is bright and white and even. Very Christmassy.
