Unburned fuel has decreased, unburned oxygen is decreased, more carbon dioxide (more fuel being burned), less carbon (soot), nox is still high (this is actually good, it means the combustion temperature is nice and hot).
I would do a once over on the spark plug gap, make sure the coolant temp sensor is ineed working properly. Replace the cat.
