I work with animation & video, so I have a good eye for details.
The Apple Mini-Led implementation is incredible for average use and film watching at 24fps; most importantly it doesn't suffer from burn in, which is vital for desktop/laptop use.
That said, the backlight is not fast enough to response to quick content.
I tested a 2021 16" for a few days, and I loved it, but working on any animated content on a dark background was horrendous, especially with the quite severe ghosting the panel suffered from.
On the other hand oleds are a terrible choice for using static interfaces, due to the burn in problem.
There's also the sub-pixel arrangement of oleds that makes reading text harder than LEDs.
Oddly enough my industry (animation) is one of the few areas of expertise where the good ol' humble LED is still king.
Even in large production studios, you only see classic LEDs, however quite expensive models.
My dream would be for one day for the burn-in problem and the sub-pixel arrangement issues of OLEDs to be solved, as the technology gives you the best possible image quality.
