Issue description

When I add a skybox with a .hdr or .exr texture, it looks good on the Forward+ and Mobile renderers, but not with the Compatibility renderer. See images:

Expected (rendered with Forward+):

Actual (rendered with Compatibility):

Steps to reproduce

1. Create project
2. Add camera
3. Add WorldEnvironment
4. Set the background to Sky, and set the Sky Material to a PanoramicSky, and set the Panorama to a HDR image

• This texture was used in the above images

6. Observe how it looks good in Forward+ and Mobile, but not in Compatibility
