Short description of error
With recent versions of Blender, using the compositor Denoise node; all Prefilter settings appear to output 'Fast'.

Exact steps for others to reproduce the error
Compositing Denoise node issue.blend

open the above 'Compositing Denoise node issue.blend' and press F12 (renders quickly)
close the render window
in the Compositing window switch between Composite and ViewLayer**

Render panel and Denoise node Prefilter are both set to 'Accurate', so the result should appear the same.

ViewLayer - Accurate

Composit - Accurate

Changing the render panel Prefilter to 'Fast', re-render, now ViewLayer and Composit match no matter which Denoise node Prefilter setting is chosen.

ViewLayer - Fast

**In 2.9.3 its "View Layer", while in 3.0.0 "ViewLayer".
If the change is intentional due EXR issues, to improve readability, maybe there could be an underscore 'View_Layer'?

Kind regards.
PS: Samples deliberately set to 256 to help highlight denosing differences.

I can confirm.

CC @manzanilla as it's probably caused by one of the patches between ecb8a574c7 - a3610c451a
