There are reddit communities (I admittedly don't remember which, but could probably be found from a simple search) where people will offer their photo editing skills to touch up the photo, often for free. Could be worth trying a real human if the robots are going full HAL 9000 and telling you they can't do it.

People sometimes do it for free ("my son died, and this is the only photo I have") or for an agreed upon tip.
