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.
 
Yes, the retina mini seems to be a total flop, you're right.

Thank God. I was worried the retina Mini was a total flop.
