I'd say the opposite - OOP is the paradigm that does the most to hide your data, hiding it within these encapsulated actors where you can't access it directly or even see what and where you have.
I would have thought that encapsulation hides the way data is processed, stored, and moved around. But the data itself is always available in my experience.
Suppose the data is in a private field of an object deep in the object graph. How do you get it? You can't, by design - that object's public interface may expose some aspects of the data, but you're not meant to access the actual raw data.
