It would also be possible to use the PV for IR, so that when adjusting the scene, you are adjusting it for how it looks in PV, and then you will know for sure what you will get when using any sort of batch rendering, animations, etc. that will save from the PV.
Making both PV and VFB look the same is non-trivial, related to translating wideRGB rendering space into visible screen RGB, where the more complete solutions would in fact have to be in the core and would need work there (so, affecting 3ds Max too). So while we have it on file as needing looking into, there's no timeframe for when that might be possible at the moment.
