Inconsistency between viewport and exported renders using Lumen and manual exposure

Reported in SF [Link Removed]

Exported renders with Lumen can appear overexposed compared to the viewport renders, even when disabling auto-exposure and manually setting the exposure values.

This does not appear to occur on all scenes, and I was not able to reproduce on the New scene, however this occurs consistently on the client file.

1. Open the .tm file
2. Review the images and take note of the Camera > Exposure and Lumen rendering settings, and the viewport renders of the images
3. Export the images
4. Compare the exported images with the viewport

Result: The renders are overexposed and do not match the viewport renders with the specified manual exposure values.
