Robert, one workaround is to export your image, then open it in Apple Preview.  Preview allows you to view an image with different profiles.  So, you can download the paper and/or printer profiles, and use Preview to view how the image would look when printed.  It’s similar to the profile view in Lightroom Classic, just not as integrated as you’ll need to go back to Nitro, make adjustments, re-export, and re-view in Preview with the profile.
