It's a good deal because the customer will have to buy another one after 3 or 4 years due to burn in or the blue wearing out. It's a great deal for the vendor.
(Continues to lament that we can't have both true black and a display technology that won't burn in or wear out quickly).
I had to check the date because that ceased to be an issue a couple of years ago. My LG OLED gets around 70-80hrs a week of use due to me working nights and the wife working days and its now almost 2 years old with no sign of burn in and the blue is still where it should be, maybe because I had my TV calibrated which resulted in blue being reduced by between 8% and 10% from 20 IRE to 100 IRE. It went from this to this after calibration.
