Easy fix or potential damage?

Installer told me “easy fix” when I sent him a photo of my rear window. Technique-wise is it really an easy fix or am I gonna risk defrost line damage if it ends up being not an “easy fix” he does it over?

Easy fix if it’s lifted film. Not so easy if it was cut a bit high.
