My HDRIs + Shader Previews are dim/desaturated and it's affecting my material output Why does it look like this? This appears to be affecting both Eevee and Cycles in similar ways, although I understand the shader view is Eevee only. My Cycles previews are also very &quot;bright&quot; or desaturated. It is very hard to get any darkness into them. The HDRIs themselves look desaturated in the background.

If you set up this same shader it'll appear darker for you.
When I open a new project it goes back to the fully opaque look and my HDRIs are also fixed. I can obviously give up trying to fix this and just start a new project and import the assets but I prefer to know why this happened so I can fix it.
It looks like your View Transform has been set to Filmic Log. Setting it back to either Filmic or Standard should fix your problem.
