Not really by any meaningful use of the world "sharply". I would point out Falcon 9 had 1 partial failure (flight 4) and 1 complete failure (flight 19) in the first 20 flights and it wasn't uninsurable. We went through the same gnashing of teeth with F9. Claims of doom and it was uninsurable. That they would see contact cancellations left and right. None of that happened.
Now if BO loses 3 of the next 4 payloads ok they got a problem but there is nothing to suggest that will happen.
I certainly wouldn't want to be the insurance company who wrote the NG-3 policy. They are likely drinking pepto and tums cocktails tonight.
