Can you show us the alignment report so we know the whole picture and ballpark of camber difference.

There is minor play in connecting points but if summed up, it can make a difference for example if the shocks or lower arm inside bush is torqued with/without weight on. Bear in mind that for example the shocks can be distorted for example from a side impact accident causing significant alignment issue even if you can't see any problem on the part with naked eye.
