Ah. Apologies for spouting pedantic semantics but, that one is technically an LCD display, backlit by LED, same concept as the original Elektron displays. (Apparently the same one installed by this ‘naut: Analog Keys - New LCD Screen)
An “LED Dot Matrix” display would be an array of tiny LEDs, not a backlit LCD.
I’ve just noticed many of that seller’s products are described as “LED Dot Matrix” when they are actually backlit LCDs.
(But, no slight to them, just semantics. They offer an impressive array of all sorts of display types for upgrading synths, and folks seem very happy with them. That one in particular is a definite upgrade from the original. I’m considering getting one myself!)
