Not really. It gets a handle to the cached object and then determines if
this is valid to send in response to the request.

This is the object identity yes. The data is not there but retreiveable
using the store functions by knowing the StoreEntry. The data may be on
disk or in memory (or both, or combination thereof).

For this you need to read the object headers by first creating a store
client by calling storeClientListAdd and then read data from there with
storeClientCopy, or just hook into the client reply processing after the
reply headers have been read. See clientSendMoreData.
