+1. The grain on the OLED I only notice sometimes, in specific situations, whereas the ghosting on the mini LED displays was always noticeable.So you get a tiny bit of grain in extremely specific cases that you still need to look extremely hard for, but fixed the ghosting, blooming, latency issues. The mini LED was great, the OLED is better, to me.
Despite not being flawless it's a clear improvement over prior displays. Whether it's worth the upgrade is personal preference, but to put it simply, I would still take this display with the grain over the mini LED one even if Apple offered that in a M4 configuration.
