ActiveShade and Production are two different render settings. Meaning, whatever you do in Activeshade isn't copied to Production. To use the IPR, use the Arnold render View and stay in Production mode. No need to jump between the different modes.

Also, press 8 and remove any exposure control

You have the Arnold Imagers for Exposure, Tonemapping, etc.
