As for through tickets, as indicated above I have successfully claimed for a long delay to an Island Line destination caused by a shorter (even sub-DR threshold) delay on the mainland which caused me to have to wait an hour for the next ferry. But on those occasions Wightlink then ran to time and did not cause further delay in reaching the island. The grey area is what happens if they too run late and add to the overall delay.
That's a delayed train causing you to miss the ferry. That's different. The DR threshold isn't relevant mid-journey, all that is relevant is the published connection time.
