I can see why you would be frustrated if you thought that these were Presets and acted like Presets, it’s actually quite different. And yes we are well aware that these cannot be applied to new layers because they are not presets built on top of a layer and they are not designed in Lightroom. The entire purpose and power behind these as a much stronger starting point. It's a newer concept and quite a bit more powerful, but they are not presets so let me try and explain the main difference.
These were built in Cube files in 3D LUT Creator that allow for much more powerful color transformations that cannot exist in Capture One alone. These colors aren't achievable to start with before editing in the traditional method. The way these were designed give you the ability to start with your file in a much stronger place, but they aren't applied to a new layer using the sliders in Capture One. So re-thinking the workflow is step #1.
If these were presets, they would just be saved recipes that we came up with in Capture One Pro that anyone can do and anyone can sell. This doesn't add any more capabilities to your images, it's just using someone else's pre-determined arrangements for some sliders.
Earth Oliver designed these specific profiles to be a starting point for the RAW level and we built these as cube files, and then formatted and imported them into Capture One Pro. The only actual slider that doesn't work is the opacity slider because this isn't a layer on top of your RAW files, it's actually your new RAW file and you build your own presets on TOP of this, or edit and retouch/cleanup in Photoshop. This doesn't work because this color transformation is happening at the RAW level, so it is the same reason that the Layers Opacity slider doesn't work when you open a RAW image, because there is no layer behind it.
So the workflow is a little new, but the idea is the same and the results are quite different.
