I don't see any gyno...it's just the way the pecs are shaped. When lean, pecs will be defined with no lumps.
I actually think that looks better with pecs...the hanging look. Not like a woman's breasts...like the way Johnny Jackson or Arnold had that pec hang.
Big Ach - you're lucky. You have good lean face even in the off-season. I have to get sub 10% for my face not to look like a balloon.
