Most post applications still seem to get the settings wrong with IPP2, so I just override the Red settings on every project. The apps should however read the camera metadata and set the parameters correctly... Not even Scratch does, though. 

I have the luxury of being in control of the image through post on most of my projects though.

Assimilate's Mazze told me once that with Red's IPP2 some of the parameters aren't specified in the metadata, so Scratch is going with its default settings, which don't match the settings used for on-set monitoring. I suppose either Red needs to update the metadata to ensure that the defaults are better, or educate the app developers better to ensure that they don't hose up those settings.
