I just went through a similar situation with a few leaves on one of our plants. We didn't move the light in time either. The leaves that were burnt actually were only burned towards the last part of the leaves so we just waited to see what happened.

The leaves retained their green and stayed alive very healthily. I think this happened however only because the leaves were only burned on about 10% overall. I would recommend removing leaves that are burned beyond the point of return like maybe 50% of the leaves.
