thats a great Q bryony as i just looked at a pair of diamonds and the male has heat burn scares on his tail area he is a healthy looking snake but has white scares.
I had a big Diamond that had bad scaring on it and he never had any problems sloughing, of the three scars he had two remained and never reduced and one superficial one disappeared completely.
Just so as you know I got him already injured from his owner who I gave the choice of handing him over or I would call NPWS. he gave him to me but I called them anyway.
