How to reproduce:
1. Create a new 3D URP project
2. Download and import any HDRI (.exr) image
3. In the Edit → Project Settings → Player menu, enable the “Allow HDR Display Output“ and “Use HDR Display Output“ checkboxes
4. Select the image and set the Texture Shape to “Cube“, then apply the changes in the Inspector
5. Create a Reflection Probe in the Hierarchy
6. Set its Type to “Custom“
7. Assign the Cubemap field the new texture
8. Open File → Build Profiles
9. Switch to the Android Platform
10. After domain reload and asset reimport, select the Reflection Probe in the Hierarchy and observe the “Cubemap“ field
Expected result: The previously assigned Cubemap Texture remains assigned
Actual result: A default Cubemap Texture is assigned instead
