Warranty it for 10 years parts and labor and THEN I'll consider getting an OLED monitor. OLED monitors are the most expensive, or second only behind the GPU, computer component and can easily surpass $1000, and one of the worst things to resell, with that value being basically zero if it has burn in.
I don't know about you, but even at 3 years if the monitor is $1500, effectively renting it for $500 a year just doesn't make sense to me, not when IPS monitors, even 4K ones, come with 144hz+ refresh rates (with 2560x1440 pulling 165hz+), very wide color gamuts covering 100% or more of AdobeRGB, DCI-P3, and 80%+ of Rec.2020, and have effectively zero burn in risk.
I own one such monitor, the Corsair Xeneon 32UHD144, which is now $750 (or less), and would recommend it every day over an OLED even if it were priced exactly the same.
