\ \Dzt distributions for isolated-prompt photon-hadron correlations measured in \PbPb collisions at \snnfive for three centrality classes: 0--30\% (left), 30--50\% (middle), and 50--90\% (right). The boxes and vertical lines represent the systematic and statistical uncertainties, respectively. Different theory predictions are shown: an NLO pQCD calculation including energy loss  (pink line and uncertainty band), and from CoLBT-hydro  (cyan-dashed line and uncertainty band). Also, an NLO pQCD prediction for \pp collisions at \sfive is shown (green line and uncertainty band).
