Worked: Never?
Short description of error
If you're using Cycles, device set to GPU, and are in the rendered view mode, if you then select viewport denoising with OIDN the viewport will fail to render and you'll receive a "Denoiser type not supported by compute device"

However, if you select the denoising option before going into rendered mode, things will work fine. See steps below.

Exact steps for others to reproduce the error

Start with default scene
Enable Cycles, set the device to GPU, AND enable Viewport denoising set to OIDN
Switch to rendered mode
Things work fine. Toggle the viewport denoising option on and off. Still works fine.
Go back to Solid shading mode AND disable Viewport denoising
Go back to Rendered mode. Works fine
Enable Viewport denoising now. Fails

The computation of OpenImageDenoise is happening on the CPU. However, if it works or not shouldn't depend on the order of operations, so even if this wouldn't be supported in ~~newer versions~~ because of a reason unknown to me, it should behave consistently.

I have to correct myself, the same issue can be reproduced in 2.91.0.
