The owner if my LFS has noticed that, regardless of color, the ones he receives as L128 all have full spotting and the L200 he gets only have it back to the dorsal fin area. And their display L128 is now 7" and as green an the typical L200 except for mild blue at the fin's edges. The pleco above looks to have some blue wash in the fins as well, so I'd think (based on heresay) the above pleco to be L128. Either way, they are pretty much the perfect pleco for most medium to large semi-aggressive tanks. I love mine.
