      abstract     = {Prompt photons are important yet challenging to observe in
                      relativistic heavy-ion collisions, as they are produced in
                      the early stages and traverse almost the entire QGP medium
                      without interaction. Experimental analyses typically employ
                      isolation cuts, in the hope to identify prompt photons. Most
                      theoretical studies consider only events with actual prompt
                      photons, assuming no contribution from isolated non-prompt
                      photons to reduce computational cost. For the first time, we
                      present a study that compares simulation results generated
                      using inclusive (bremsstrahlung) and prompt-photon events
                      with multiple experimental observables for both p − p and
                      Pb − Pb collisions at 5.02 TeV. Simulations are carried
                      out using the multi-stage JETSCAPE framework tuned to
                      describe the quenching of jets and hadrons. Isolated
                      non-prompt photons are generated in hard photon
                      bremsstrahlung, where the photon is radiated at a sufficient
                      angle to the jet. Several photon triggered jet and jet
                      substructure observables show significant contributions from
                      inclusive photons, yielding an improvement in comparison
                      with experimental data. Novel photon triggered jet
                      substructure observables are also expected to show new
                      structures, yet to be detected in experiment. This effort
                      examines the significance of isolated nonprompt photons
                      using parameters tuned for a simultaneous description of the
                      leading hadron and jet spectrum, and thus provides an
                      independent verification of the multistage evolution
                      framework.},
