A Federal Court in Australia ordered LG Electronics to pay a fine of $160,000 AUD to two consumers after LG refused to repair, replace or refund OLED TVs that exhibited burn in after less than a year of use.
Under the Australian law, consumers who purchased faulty products are entitled to a repair, refund or replacement - even if the warranty does not apply or has come to an end. The two OLED TVs were bought in 2013.
Burn-in has been an issue with LG's OLED TVs since 2013 when it first launched these products. In 2018 LG had to replace some OLED TVs in Korea's Incheon airport with LCDs after the OLEDs developed serious burn-in issues, and later in 2018 Rtings.com performed some tests that showed serious burn-in in LG's OLED TVs after only 4,000 hours of use.
I have an OLED TV since 2016 (LG's OLEDB6) and the TV still works perfectly without any burn-in. UK-based HDTVTest recently performed a 3,700 hour test that shows that burn-in can be avoided if you vary the content displayed in the TV, which makes sense.

A was at a local casino while they were doing software upgrades on the slot-machines. There were entire rows of machines with a "maintenance" mode displayed on the screens. About half of the screens had severe burn-in from displaying the same graphics 24/7/365. The curved LCD screen slots didn't have any burn-in, but the OLED ones were really bad. They would have been unwatchable if anything other than their normal slot-machine graphics were on the screen.
This is probably an extreme case, but like the airport flight-info OLEDs, some commercial applications might be better off with LCD's.
