How to reproduce:
1. Open the attached “IN-112730” project
2. Open the “SampleScene”
3. Ensure that APV probes are displayed (Window → Analysis → Rendering Debugger → Probe Volumes → Display Probes)
4. Under the “unlit_material” GameObject in the Hierarchy, double-click the “Cube” GameObject to focus on it
5. Observe the APV probes in the room
6. Under the “shader_graph” GameObject in the Hierarchy, double-click the “Cube” GameObject
7. Observe the APV probes in the room

Expected result: The APV probes in both rooms display a dark gray color
Actual result: The APV probes in step 5 display a dark gray color, while the APV probes in step 7 are black

Reproducible with: 2023.1.0a1, 6000.0.56f1, 6000.2.1f1, 6000.3.0a5

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Note: Both the “unlit_material” and “shader_graph” GameObjects contain a child GameObject named “ceil”. One uses a material using the “Universal Render Pipeline/Lit” shader, and the other uses a shader made with Shader Graph. They are both white with the alpha channel set to “0.39”
