queryInstantiatedChaincodes method fails when setting explorer with non-admin fabric client access credentials

With reference to below Jira we can see the implementation approach taken for this method 
https://jira.hyperledger.org/browse/BE-750
 
From Fabric end we have two different system chaincodes to handle the 1.x(install-instantiate model) and 2.x(lifecycle)model
 
lscc: manages the chaincode lifecycle for the 1.x releases of Fabric.
_lifecycle: implements the Fabric chaincode lifecycle process
 
For Explorer connected to Fabric with 1.x channel application capability "lscc" chaincode is contacted and "GetChaincodes" inside it retrieves all the instantiated chaincodes
 
whereas 
For Explorer connected to Fabric with 2.x channel application capability "_lifecycle" chaincode is contacted and "QueryInstalledChaincodes" inside fails from fabric end itself to fetch the list of installed chaincodes
 
Can we update this method to display list of committed  chaincodes on the network, instead of fetching installed chaincodes
