If you have AppleCare+, Apple should give you a refurbished, replacement iPad Pro for a small fee of $49 U.S.D.
I think the Apple Stores have refurbished product in stores and can do the replacement in store.
Also, Apple DOES have a screen repair program, but that involves making a repair claim and actually mailing your iPad Pro, DIRECTLY, to Apple in Cupertino, CA.

Depending how bad or deep the scratches are, you could try applying a couple of thin coats of straight, non-abrasive liquid car wax or couple of thin coats of non-abrasive auto paste wax (stay away from the iPad's edges and home button) to see if the wax covers over/fills in the scratches.
Use a non-abrasive pad or cloth.
Let the wax haze slightly then but the glass with another non-abrasive cloth.
At this point, whaddya got to lose. The damage is already done.
Good Luck to You!
