No, they still get burn in. They also aren't very bright out of the box, and they get dimmer over time. They're also more expensive than LCDs despite having a limited lifespan. I've never been a fan of OLEDs for these reasons and my theory is that manufacturers want to sell them because they have a limited life span so they can sell more.
MicroLED I'm super pumped for though. No clue when we can actually expect to buy them though.
