Our four 6.5yo display 7 stripes. IDK what "bold" means, it is not a precise term. I can clearly see and count 7 and the middle 5 are the thickest. There is a faint and short one right below the dorsal fin - 8th?? You can count them and see them as well as I can, e.g. in the video thumbnail above. I'd say I see 6 bold stripes, if the last one, the lowest on the tummy, can be deemed not as prominent.
Plus the lips on our 4 are indeed protruding a bit at the mouth corners.
So I conclude ours are labeamajor, not jullieni.
