I understand, I did a little bit researching on this. It seems that Path-Tracing is quite experimental which probably is the reason that the reflections are not the same.
https://docs.unrealengine.com/en-us/…ing/PathTracer if you see in this link, there is a picture that shows the differences between Raytracing and Path-tracing. There you will notice that the reflections are also different. Also there it says that some materials and lighting features arent supported, could be that the reflections are part of the unsupported features.
You could try to use SSR for the Path-Tracing instead real time reflections (by changing the reflection type inside PPV to Screen Space) but… I dont know what you are trying to do tbh.
