Great for Glossy.From display expert Ross Young, this may further support why the nano display on the MacBook Pro looks better to me than the one on the Studio Display:
Big Apple display news, they have adopted quantum dots for the first time. The latest MacBook Pro's (M4) use a quantum dot (QD) film rather than a red KSF phosphor film.
In the past, Apple went with the KSF solution due to better efficiency and lack of cadmium (Cd), but the latest Cd-free QD films are very efficient, feature as good or better color gamut and better motion performance.
Edit: MacRumors covered this in more depth.
