After upgrading a project from 2019.4 to 2020.2 the environment light skybox is now yellow.

Steps to reproduce
- Clone project git@github.cds.internal.unity3d.com:unity/benchmark-office.git -b 2019.4. This project is large.
- Open it. Beware I had two occasions where my windows system blue screened and hard locked at this point, save your work.
- Open the scene found under Assets/0m/OfficeRoom.unity
Notice issue - The scene renders yellow.

Expected: The scene should not have a yellow tint.

Tested broken: Windows, 2020.2.0b1, 2020.2.0b6, 2020.2.0b8
Tested working: Windows 2019.4.12f1, 2020.1.10f1

I have not tested with any other HDRP projects. Regression checking results to follow...

I've set up runs of 2019.4, 2020.1, and 2020.2 on our internal CI. You can see screenshots and logs from each run.

Ping me for access, feel free to kick off a new build with a fixed Unity version for testing.
