Steps to Reproduce

when turn off hardware raytracing in lumen Scene viewmode there are two things look quite different comparing to Hardware raytracing enable mode
1、The surface has a black circle around the light, it seems the area where in certain narrow angle aiming to the light becomes dark.
2、It seems no bounce light(actually it has much much dark bounce light)
So the final image rendered by software raytracing mode is much darker than the scene in hardware raytracing mode

Expectation: Software raytracing should look closely to hardware
