How to reproduce:
1. Open the project “IN-117238_DDSLRGGPUUploadIssue”
2. In the Game tab, notice the metallic, rough, reflective shading
3. Change the Graphics API from Direct3D11 to Vulkan (Edit → Project Settings → Player → Other Settings → move Vulkan to the top of the list)
4. In the Game tab, notice the shading change

Expected result: The object remains metallic, rough and reflective
Actual result: The object loses the metallic, rough and reflective properties

Reproducible with: 6000.0.8f1, 6000.0.58f1, 6000.2.6f1, 6000.3.0b3, 6000.4.0a1
Could not test with: 2023.1.0a1, 6000.0.7f1 (many package dependency issues)

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

Note: The issue is only present with Vulkan, DX12 and DX11 works as expected
