OptiX Denoiser Clamping result to 1

When using the OptiX Denoiser in Katana (Katana - 3.0.5, Arnold-5.2.0.1 and a recent KtoA build and Linux), we noticed that the denoised passes are clamped to roughly 1.0. Is this a known limitation of the OptiX Denoiser?

The Optix AI Denoiser was originally trained on 8bit images so can't go to float ranges beyond 0-1.

There will be a new version of it released soon that has been trained on HDR imagery.

Thanks! Any idea when it'll be included in a core release?
