The question of energy conservation makes this question even more tricky because the OP's notion of a photon being there or not there is too coarse for quantum mechanics. In quantum, the photon can be in a superposition of there and not there... | |

The processes aren't entirely different, but distinguishing them could help eliminate a very commonly held belief that the universe is full of single photons flying around and interacting with atoms. Fock states do exist, but usually only in a laboratory. In Nature, we mostly have coherent states. | |
