MBP is miniLED, with LCD as a primary light modulator and a relatively (compared to older local dimmed displays) high-resolution backlight. I.e. you have 3456‑by‑2234 LCD pixels that filter light, but like 300-by-100 light sources (LEDs) behind it.

MicroLED (uLED) is still an exotic technology, it’s in principle similar to OLED, but with inorganic LEDs. It has better color rendering and less burn in problems, but is difficult to manufacture for now.

Basically, display technology names are deceptive, similar names may mean completely different things.
