OLED is always better than mini led IMHO. The only drawback is that OLED has burn in issue. And that's a no go in a laptop that has persistent menu bar, dock, etc. So I really think mini led is a good choice since it's better than normal IPS/LCD display but lower than OLED which has burn in issues.
just with burn issues? peak brightness, sustained higher brightness, blue led shifts aways so early...
For smartphones oled are fine, because the displays stays on for multiple sessions but short sessions ..for monitors, laptops etc...oled is no near close to miniLed...a new tech that already surpass the decades of oleds
I suspect in 4 years we will have even better miniled with even more minileds inside with even more controllable dimming zones and so on...oled now, kind of reach its potential in the big picture...
micro-Led is the future, but its very very hard to shrink down the pixels at Apple scales that it needs
So , since micro-led is so far away still....and oled reached its potential...i suspect more companies to adopt mini-led display for laptops and displays
