Education Needed Did Patina Prevent Cam Or Proof Like Or Are The Coins Neither

So just got back my first submission from ngc.
And 3 of the coins I thought had chance on either cam or pl.
But looking on ngcs horrible pictues I see a lot of patina. I did not dip the coins prior to sub.
Do you think it would have helped or not? All coins straight graded.
But I'm planing to send another round so good to get some Input.
Do you think the heavy haze can hold them back or do graders look beyond that

Sorry for breaking one coin per topic but I feel this is more of a General edjucation on the same topic.
Will post some of my pics of the coins also
