I could see an argument for the phone owner being able to request specific data off the phone, that the police could individually screen before returning to him and wiping the phone.
However if the ultimate goal is to make sure no CSAM or victim info is accidentally returned to the predator, the phone is ultimately going to have to be wiped. There are probably some data extraction companies that could make a pretty confident claim to have removed everything, but it'd be very difficult to verify.
