Understanding presets and 'custom' tone curves

In an effort to understand how my favourite preset works in Lightroom Classic, I copied all of its settings manually and applied them to a virtual copy. The only problem is my photo looks completely different to what it does if I just apply the preset to the photo.

The only difference I can see between the manual settings I've copied from the preset is that it has a LINEAR point curve, whereas the preset has a CUSTOM point curve applied under the Tone Curve module (see examples below). Both look completely linear

My question is, how do I see what the 'CUSTOM' point curve adjustments are for the preset so I can truly understand what's actually going on in the image when I use a preset? Is there any way to see this or is it IP that can be viewed?
