Mastering display color volume in the protocol is actually the target color volume
We use the terminology MDCV which intends to describe to target color volume. It might make more sense to be explicit about what this color volume really is. We could still mention that this is compatible with the MDCV.
This might be confusing and people might not make the connection between available MDCV and target color volume. On the other hand, this disconnect might be useful to stop people from blindly plugging in bogus MDCV metadata.
