I am familiar with this - the front subframe is installed too far to the driver's side. The subframe isn't located on dowels, so it can be installed in a variety of positions! If you were to shift it to the passenger side, it would even out your front camber. This is an issue on the Model S as well.
When you shift it to the right, it will increase the RF camber and decrease the LF camber. I hope that helps!
Edit: just to be clear, your installer didn't remove or install the subframe while doing the coilover installation. It isn't their fault!
