Something is definitely off about this. As others have noted, mini LED in its current form is almost a scam lol. I was watching a review of the new mini LED qleds from Samsung vs the LG OLEDs, and there's essentially no difference from previous FALD LCDs. The OLED killed it in the comparison of course.
Unless Kuo has confused mini LED with micro LED, I can't imagine the scenario where an iPad Air has OLED and the Pros don't.
The Apple Watch display is fantastic... I can't imagine Apple taking a step backwards on that either.
Kuo wouldn’t have confused Mini for Micro considering Micro is no where near production time for iPads.
