Huh. It's there for me too, now I actually look. I guess I've learned to ignore banner-shaped things at the top of web pages.
[EDITED to add:] Actually, I seem to get it for "duckduckgo bangs" and for "bang duckduckgo" but not for "duckduckgo bang". But I'm not sure it's consistent from one search to the next. Anyway, I think the reason I didn't see it before is that it wasn't there, not that I'm banner-blind.
I actually do get it for "duckduckgo bang". Maybe they're hotfixing it, or maybe some self-learning algorithm decided that this was close enough to "duckduckgo bangs"? Shooting in the dark here.
