Lightroom 4.2 uses a DNG Profile file instead of an ICC file, to work with Camera RAW files being processed.
How do I use Prism to improve upon the generic (although camera-specific) profiles that came with it? I would think I would get better results using my actual camera, not to mention the same lights.

You would probably do better... but Profile Prism edits its own profiles only.
So a Lightroom profile will not work for you.
What camera do you use?
Have you looked into Qimage and its camera profiles?
