Chasing the 8 pack, can be an exercise in futility. I have worked with body builders and I agree there is a genetic aspect to achieving this look...also it might not matter to you but the deeper muscles are where a lot of strength is so the 8 pack is all for looks. (I get it...I have chased the dream skinny thighs) But consider how much your willing to sacrifice to attain this look and once you've got it ( if it's possible, how hard it is to maintain??). Even most body builders only strip down to this super low bf level for a short term competition or photo shoot. You could embrace the body type you are.. healthy and strong comes in different shapes.
