OIDN in render properties results in blurry images compared to Denoise node #78881

Short description of error
The OIDN in the Render Properties seems to produce blurry/smudged results compared to the OIDN Denoise node in the compositor.

Denoised using the Denoise node in the compositor with Denoising Data passes. (below)

Denoised using OIDN in the Render Properties (below) -- the results look similar to denoising in the compositor without the additional denoising passes

Denoised using the Denoise node in the compositor without Denoising Data passes. (below)

All were rendered at 32 samples. As you can see, the details are barely preserved compared to the Denoise node (w/ denoising passes), especially in the floor and ceiling.

Exact steps for others to reproduce the error
I have attached an example blend file for reference.

The blend file is set up with the OIDN in render properties. And the denoise node is also set up in compositor with nodes disabled.

Results look like the OIDN in Render Properties is not using the Albedo and Normal passes as they are very similar to denoising in the compositor without additional denoising data passes.
