I know this is old, but for some reason just seen it. I have had several dl that are creped/dimpled. I don't think it is rare so if it has other qualities that are not up to par, I'd cull it.
Personally, any dl that is dimpled gets sent to the compost here, I think they look wrinkled/shriveled and I don't like it. My word to describe those is 'frumpy'.
