It's still MiniLED but I believe there was a subtle change on the M4 series that means it's slightly better about it.

It's mini-LED backlighting, to be pedantic.

I welcome your pedantry. I stand corrected, though I can’t edit the post any longer.

Localized bloom is vastly preferable to the alternative, which is the uniform bloom of a backlit LCD display.
