You're right. Everyone is interesting once they open up a little.
The goal though isn't to show how you're different from the herd, it's to show that you're better than the herd, for whichever sub-herd you're signaling membership. That strategy preserves maximum choice.
Something interesting I've noticed, is that trying to break that mold is considered negative. If you look at subreddits that tend to give out advice (typically to men) on dating profiles, they advise people to do things that make their profiles more generic.
I personally avoid dating apps, because I'm not attractive enough (or at least, not photogenic enough, somehow cameras almost always manage to clown me) and I'm not outwardly interesting enough to attract people by reducing myself down to a few pictures and text snippets.
Now I will say it's not really anyone's fault. Women looking for men probably don't see what the other women on the site's profiles look like. Likewise my profile might be a trope as well. But men do have to go out of their way to stand out to get a decent chance at a connection.
