If I recovered a file using btrfs restore, is the file that’s recovered bit perfect to the original?

I used this script to recover an accidental deletion of my .config which included PCSX2 memcard data, and I seemed to get my memcard files back, but i’m wondering if the files recovered using a script like this/btrfs restore are usually 100% bit perfect restored or is there a very sizeable chance files restore are partly corrupted? Thank you for the trouble!
