EXR patching exposure issue

[Nico Höllerich]

Steps to reproduce:

1. Download the project: https://drive.google.com/drive/folders/1zFUhZuDtp0739q1prk5OaBZQFUPbysFJ?usp=sharing

2. Open  2025-04-20-0293.pts

3. Under display set show to "HDR panorama" and exposure to -13 (see setup.png)

4. Create a small patch of the sky with image format exr and open in PT Patch Editor

5. After creating the patch, zoom a bit out and set blending to "no blend"

6. The patch is much brighter than it should be (exposure settings are not correctly calculated)

7. Setting the exposure offset of the patch to -3.66 is a workaround to correct the problem. See 2025-04-20-0293_with_corrected_patch.pts
