There are leather seat repair shops that can fix the tear/scratch so you cant even see it ever happened. They match the compounds, color, and texture in the leather and work it in using heat and then buff it smooth.
It should come out transparent enough you dont see the mark.
You will have to look in your area for a leather seat repair shop. It could cost you $20-50 dollars depending on amount of damage.
I have seen this done on leather seats, dashes, coats and its hard to tell afterwards.
good luck.
