[Runtime and Toolkit Bug]: HDRIs clipping/artifacting

Describe the bug

.exr/.hdr converted HDRIs with the NVIDIA Texture Tools Exporter using the BC6S format have severe clipping and artifacts inside the toolkit and runtime (with RR off, its a black dot, with RR on, the denoiser freaks out, causing artificing as seen in the video below)

How do you reproduce the bug?

1. Download a HDRI from PolyHaven or other CC0 source such this: https://polyhaven.com/a/rosendal_plains_1
2. Import the HDRI into NVIDIA Texture Tools, set the Format to BC6S HDR RGB, Save As... a DDS file in a place where both the toolkit and runtime can see it
3. In the toolkit, select a sphere/dome or other sky-like object, remove albedo map, set albedo color to 0, select the converted HDRI as a emissive map with the emissive intensity at 1 (changing it does not fix the issue)
4. Map gets lit as you would expect for a HDRI, but has black clipping or denoiser artifacts from areas of high luminance such as the sun or a bright light. This is observable in both the toolkit and in-game

What is the expected behavior?

The runtime should display the HDRI without clipping as shown inside NVIDIA Texture Tools/Photoshop

Start by reproducing the issue with a PolyHaven HDRI converted to BC6S HDR RGB DDS using NVIDIA Texture Tools Exporter, then compare its display in the toolkit and runtime with the source shown in Texture Tools or Photoshop. Check behavior with RR enabled and disabled; done means the HDRI displays without black clipping or denoiser artifacts in both environments.
