You need to wait for micro-LED to be safe(mini-LED is just a stepping stone)
OLED screens are now more durable than when they were first introduced over a decade ago, but OLED screens still probably won't last more than 4-5 years before the blue pixels start fading to a point where it's very noticeable.
Mini LED LCD screens represent the latest LCD screen technology. The best LCD screens are nearly as good in power efficiency, brightness, and gamut as OLED and should work for decades.
MicroLED screens have more in common with OLED than "Mini" LED screens. They are basically the best of all worlds. Better brightness, gamut, efficacy, and longevity than everything else, but currently microLED screens are only used in ultra ULTRA high-end products. Apple has bought several companies working on microLED screens over the last decade... so hopefully we'll see something soon-ish?
