False Color view PLUS clean video output

Is there any option to see false color in premiere PLUS the clean video output? I found some workarounds using LUTs to get a false color view instead of just the waveform? I found some workaround using custom LUTs to see false color in Prmere, but then you dont have a clean video view anymore and have to switch back and forth. I am thinking about maybe using my atomos shinobi small on-camera monitor with an HDMI splitter cable to color grade in premiere just to be able to see a false colour view. But maybe there is an easier option? I think there are some third party apps, but maybe they draw lots of resources..
