How to recover deleted photo from iPhone?

I had a photo which was pretty valuable for me(on my iPhone), but I accidentally deleted it(haven't done any backup etc.) Only thing I have left from this, is a profile pic. In my contacts. Is there any way to recover this photo from there?
I know that I can access contact picture on iPhone and save it to camera roll, but it's in terrible quality if I do so. Any other ways to do this?

If you never backed up and don't have cloud share turned on, then it is eternally deleted.gone
