Why Falklands service would probably preserve HMS Roberts

Would HMS Roberts have been preserved after a successful Falklands deployment?

Almost certainly, because service in both the Second World War and the Falklands would give the monitor exceptional historical significance.

If Roberts had returned to service, she would combine Second World War heritage with a new combat record in 1982. That history would make postwar preservation highly likely. Her condition after the deployment might require carrying her home aboard a heavy-lift ship rather than sailing independently. The final location would still be uncertain, with Portsmouth, Plymouth, and a London dock all raised, but disposal would be much less plausible.
