Richard is correct. The original is unaffected. There's possibly confusion over the particular role Process Recipes have within C1.
The selected Process Recipes determine a lot, have a look at your Histogram as you click through a few different ones, for example. Note, not your Levels tool, that's independent, but your Process Recipe will remap its own representation of the histogram according to the color space and parameters you've set up within the recipe.
One thing they do is affect how cropping is communicated. The measure indicated on the dimensions of the image in the Viewer stems from the Process Recipe, so it could state it in inches for a full size output selected. If you had an output of 1200 pixels across it would indicate that instead. The original file is not what is displayed, it's the outcome according to the Process Recipe.
You can set a default profile for this in the View Menu: View>Proof Profile and select, it defaults to 'selected recipe'.
