To be honest its not pretty but most likely will grow right out of that and will never make any difference in the long run.
The scar at the bottom is the only concerning part. As long as that doesnt get worse I would worry about it much.
It's missing a third of the cambium layer around the base. Probably a lot more prone to infection at that point as well. Plus it's starting to flake or split right there. Anyways mistakes happen all the time, I make plenty of them.
I'm not going to get all excited at this point, I'll just wait for his response.
In hindsight I should have taken a photo of it the way it was shipped but I didn't notice the scar because it was heavily wrapped with not one, not two but three types of tape. Clear carton sealing tape, masking tape and finally electric tape lol. When I cut through the tape and quickly moved the root ball to its new home, only then did I notice the problem.
