> but the older panels we're talking about were multiplexed, so the data would only have to go through the (shift registers for the) previous leds on the same row
True, but those tend to flicker because of that, they are not on steadily and that robs you of a lot of potential to create shades (and you'd need RGB individually, these WS2812B's are 3 LEDs in a single package).
Each LED decodes, stores and regenerates the signal to preserve integrity, that's why it work, there is about 200 ns lag for every LED that you add to a string.
