So is DI usually referring to automatic framework-wiring DI? Cause I constantly pass dependencies in as arguments and call it DI.

DI can be manual DI - passing dependencies. I think the hallmark is lack of "new" in your classes (or probably lack of specific imports in a non OO idiomatic language like JS)

IoC is more about design than dependency resolution mechanisms.
