Why is the black ceramic border around my 2016 Toyota Camry Hybrid replacement windshield a different width for each side? Safelite used a Toyota OEM windshield

 

Don't know.

The boarder is there to aid in windshield adhesive bonding, protect the adhesive from UV and hide it and any gap in body/interior fit..

Perhaps the adhesive pattern is not uniform around the glass or there is a larger gap on one side then the other..
