You might. Pretty much anything that emits or filters light will degrade over time, and I seem to recall that OLEDs have a shorter time-to-50%-output decay curve than regular LEDs. That's fairly common for a new technology though.. the first few years are devoted to making it work at all, then incremental improvements make the technology progressively more bulletproof.
An OLED screen wouldn't have the classic "see it even when the device is turned off" burn-in of an old phosphor CRT, but the pixels that get used most would produce less light than the ones that get used the least.

I don't have specific numbers for the degradation times on the OLEDs we sell, but I *think* the half-life for OLEDs in general is somewhere around 10,000-15,000 hours. A year is roughly 8000 hours, so that's 1-2 years running 24x7, 2-4 years running 12 hours a day, or 3-6 years running 8 hours a day.
When you void a product warranty, you give up your right to sue the manufacturer if something goes wrong and accept full responsibility for whatever happens next. And then you truly own the product.
