Burn In

I bought an open box LG OLED yesterday from Best Buy. Condition was good and there were no comments on the item. I signed up for the BestBuy Plus membership but did not get the geek squad protection plan. After having the TV for a day, I’ve come to find out that there’s TV has over 4,000 hours on it and there is OLED burn in. I really love this TV, but I also really love it at the price. How likely am I to get an exchange for a new version of this TV without paying the difference? Should I purchase the protection plan and make a claim for it being defective?
