Does anyone know how to adjust the trunk alignment on a GS?

My 2007, is out a little, with the RHS top edge raised around an 1/8th more than the left which is flush.

Is this a dealer only fix, or is it something that I can do?

 

Yeah my driver side is a bit off too and i noticed on other Lexus models too have the same issue ... it seems the factory can only get either side right lol

 

mine too...the driverside isnt flush...
