I found one strange thing in one of the presets: The DxO optical corrections only preset lists “unsharp mask” as active, it does not display it in the GUI though.
As we can see (left bubble), the DxO optical corrections only preset was applied.
This preset (re)sets all tools to whatever values and whether they should be active or not.
Looking into the preset that is in the app (middle bubble), I see “UnsharpMaskActive = true”, which imo means that the tool should be acting on the image, which it doesn’t. I can switch USM on and off and see a sharper image when USM is on. So, while the preset says true, the tool is off (right bubble).
