Question about knog. Blinder set

Are there different light patterns for these knogs? According to the internet search, there are e.g. "rectangles" "X" "shaft board" or the skull ... At the same time there are two practically identical "knog. Bliner Set "s at Galaxus with the only difference in the number of product images and different patterns? (Product no. 12858998 / 12858999). Or is it exactly the pattern that is the difference and there are no modes?
