I think this is just how denoiser works and we have to deal with it but maybe it is actually a Bug so here we are.

System Information
Operating system: Ubuntu 18.04

Blender Version
Broken: 2.81 daba3e871f and f2cab8267f

When using Blender denoise node in the compositor it kill the details like this (zoom in) this is an original image, after denoise node is applied it looks like this
Notice that all carbon fiber details are gone and I have single color surface instead, I tried using outputs from Denoise pass and also enabling only Diffuse color and Normal outputs and it gives same results even if I only plug in noisy image.

Here is the .blend file testfile.blend
(Note that I wouldn't use denoiser because of these parts but because some others that I removed from file in order to shrink down file size) and there is HDRI packed but I don't know if I did it properly so here is link to it if that matters https:*hdrihaven.com/hdri/?h=mall_parking_lot

Please read starting from here:
https://blenderartists.org/t/intel-open-image-denoise-released-for-2-81/1144893/115

Feel free to ask more questions in that thread of Blender artists forum.

Edit:
Here is your test file with LordOdin node setup:
testfile_mod.blend
This may require a lot of RAM, about 14GB. Excessive RAM usage is still a problem to solve.
Edit 2:
I have uploaded the file again. I had made a mistake earlier.

I tried it and it froze my PC because I don't have that amount of RAM.

I still have to read through all of the above mentioned tests/nodesetups, but do we agree here, that this is not really to be considered a bug?

There is a bug report regarding memory usage here: #69006 (OIDN: RAM increases proportionally with each Denoise node used).

Improving denoising to preserve details better is always useful, but that's research and improvements, not a bug.
