Lighting Test for Unreal Engine 5
The goal is lighting has correctness and neutral.
Engine Users would be able to use these test scenes to verify that the lighting is correct and neutral for the various Unreal Engine rendering methods.
Lumen
Hardware Ray Tracing (HWRT)
Software Ray Tracing (SWRT)
Screen Space Reflection (SSR)
Screen Space Global Illumination (SSGI)
Global Illumination use Lumen
Reflection use Lumen
Use Hardware Ray Tracing when available

This looks like mix in diffuse(base color) to mirror plane...
UE5 Path Tracing is also same result...

3. Perfect Mirror Weak White Plane
Reference
Lumen
Path Tracing (UE5)
Making Base Color as close to black as possible will bring you closer to the reference image.
However, the reflection of the floor will also be weakened...
UE5 Path Tracing is also same result...
