Not really. There are no "selfies" of voyagers, Dawn, New Horizons, Juno etc. T There ARE pictures/data from what these have produced. JWST will be no different

Even Hubble didnt really have any of that that I am aware of. Most of the pictures of hubble itself are from servicing missions. Sure you have some rover selfies on Mars, but thats not the sole purpose of the instruments, quite the contrary really.
