BT,
L190 and L191 are easy to tell apart.

L191 is dull eye, broken squiggly line. The lines tend to break up towards the tail end. As juveniles the grey is very dark.

L190 is pin-striped (straight line)

My guess is your fish is an L191 as both AI and Xian Leng have been bringing in quite a few L191 of late. Not many L190 available of late.
