But, in the hypothetical counter example where the prosecution had evidence of you using the encrypted volume (let's say, a convincing photograph or video), would you then grant the prosecution the right to compel the decrypted information?

That actually was answered by a court quite recently, and is mentioned in the OP.

A guy going through border guards control somehow let them see he had illegal images on his laptop. The court concluded he is no longer protected by Fifth Amendment because of that, and ordered him to EITHER reveal the password OR give access to the (encrypted) content in question in some other way.
