You would definitely need to apply this profile lastly to your processed TIFFs created from your RAW software. And ensure you initially process them in your RAW converter in exactly the same way as the original TIFF that you created and profiled.
I’m unfamiliar with the RAW software you’re using, but you should be able to save the settings for use on future shots.
Due to the slight difference in colour temperature of your flash units under differering power, you might want to create a few profiles for different shooting apertures and corresponding flash power.
Hope this helps!
