[Denoising] Denoising using OpenImage or Optix is introducing dark borders to UV charts in intensity

Progressive Lightmapper

Repro:
01 - Downloadload and install the required editor version: -r 7bd0b0ebb78d
02 - Pull the content repo from https://ono.unity3d.com/test-data/gi-tests/ArchVizPRO-Interior-Vol6
03 - Update to content revision: 6f47bfe08488
04 - Generate lighting using the settings stored in the Scene. All this to complete (3-4 mins)
05 - Navigate in the Scene to the upstairs bedroom area shown in the screenshot.
06 - Select the wall mesh shown in the screenshots.
07 -Open the baked lightmap view for this mesh by double clicking lightmap preview in the inspector.
08 - Repeat all this using either Optix or OpenImage denoisers for comparison.

Note:
Around the edges of UV shells in the baked lightmap view there are dark edges with a kind of sawtooth patina. These are seemingly introduced by the denoisers. Padding wont fix the issue. This corruption is different between the denoisers, which is super odd.

Expected:
There should not be dark edges where walls meet in this Scene. We kinda get away with it because it looks like AO, but is actually a bug. Denoised results should ideally be consistent between denoisers.

    If this is won't fix, can we be given a view as to how it will be fixed, i.e. are we waiting for a 3rd party to resolve this?

    I am concerned that this is being put down to the way 2 different denoisers work, yet it would seem off that 2 separate denoisers produce the same errors. Occam's Razor might suggest that the error is not outside of unity's control..
