You're right that LED isn't immune from burn-in, however, it is much more resistant to it, and isn't necessarily permanent either. Leaving an LED display off for a few days, often less, can be enough to bring it back to normal.
Another artifact OLED displays have is their PenTile subpixel arrangement to compensate for the red, blue, and green organic compounds degrading at different rates. Hopefully micro LED brings us OLED quality with LCD reliability.

Those LED displays you can get in retail are nowhere close in die size to what microled is. Those conventional 1080P led displays with <1mm pitch already demonstrate very visible burnins. There is one in a hotel nearby that is only 4 moths old, and I can already distinguish an imprint from the brand logo, they seem to have unknowingly ran it on maximum brightness though.

Are you seeing burnin of the LEDs, or image retention on the LCD? LED burn in might look more like noticeably different white levels across the different local dimming areas, especially if it gets worse over time related to static brightness differences in the displayed image.
