No.
Even taking into account the fact that RGB is based on bitcoin transaction graph (which, in turn, is based on bitcoin timechain), RGB itself is not a 'blockchain'. It’s a form of a DAG, where you don’t have the data on a complete state of the network, ever.
From the moment you create a smart contract and transfer the state to some other party, you have neither the control over that state (only the new state owner has it), nor the information on how that state actually evolved.
