Do electroluminescent quantum dot displays suffer from "burn-in" effect like OLED displays?

To my knowledge, compared to oled, elqd displays will be very cheap to mass produce using ink jet printing process. Quantum dots can have very narrow FWHM which allows displays to have wider color gamut of >90% rec2020. The response times of quantum dots are also faster than oled. Most importantly, it is also self-emissive like OLED.


However, one of the biggest concerns I have is if it suffers the same "burn-in" effect like OLED. To my knowledge, the challenge of commercializing ELQD displays is that the lifetime of the blue emitter currently only lasts a couple of hours at 1000 nits. However, I'm not sure if the term "burn-in" is separate from "lifetime." In an OLED display, when a static logo is shown for a really long time without any "burn-in" compensation technologies, the logo will burn in and the respective pixels will permanently shift colors which is very noticeable. I wonder if the same occurs with ELQD displays. In addition, I have also read somewhere that quantum dots are also not truly inorganic materials because the "ligands" are organic.
