********************
    Release was not present in Helm.  Diff will show entire contents as new.
********************
If I am interpreting this right, this means that there's no diff between a local state and the deployment in the cluster. Is this correct?
                        
Just the opposite, this means
helmdidn't find such release in the cluster anddiffwill show you entire contents as new vs only showing you differences.At any point you can do
helm listto see what releases you have deployed.
