Well, possibly I miss something, because I wouldn't recognize a Deathly Hallows logo if I see one. (I assume this is rather from the movies?). But there are occasional references to Harry Potter I have seen.
Apart from that, I would say Harry Porter represents some things.
The glass eyed bullied nerd, that steps into a magical realm to become a superhero. In general, the concept of a fantastic magical realm hidden besides this dull concrete reality. But those are old tropes I would think and unlike with Matrix(blue pill, red pill), Star Wars (may the force be with you, the dark side), Lord of the rings (The ring of power that corrupts), I don't see such strong concepts coming from Harry Porter that
"supplies metaphors and narratives through which nearly everyone today interprets the world around them"
Just my impression, I don't have a strong opinion here, rather curious what I might miss.
