Can't help but think that whatever supposedly "happened" is not that relevant, what matters is the measurement. Clearly "the photon" is only the effect of the interaction between light and the act of measuring it. You just can't remove the measurement from the phenomenon. In our reality ("to us"), light doesn't make sense if it's not measured, and the result of that measurement is not light itself, but the product or outcome of the interaction of the measuring device/method and whatever "light is" (when not being measured), if light can even exist without being measured (which is unknowable).
