Is it permanent? No. Once the stress is eliminated the leaves relax and return to normal. But there may be other stress causes at work besides the over-watering. Pests? Different soil mix? Different location? Different nutrient levels? Different age of the plant? Different sun exposure, even different amount of root damage from the over-watering. Even different DTM's can affect growth rates.

I had permanent leaf roll on several plants last year. We had a wet spring, causing the leaves to roll, and those older leaves stayed rolled up the whole season. But, the soil under those plants was deeply worked and had a lot of clay so part of the soil could have remained fairly wet the whole season even though we had a 6 week drought.

california,

Here is my one Black Krim. I had some leaf roll when we had some rain recently, but they seem to have "relaxed" today:
