Read page 2515 of the Resolve 17 manual, "Limitations When Grading With the Viewer on a Computer Display." This explains why it's unwise to try to use a computer display for final color correction.The same problem exists with the "Clean Feed" output, since it's not color managed.
Don't try to make judgements on uncalibrated GUI displays. That will lead down a perilous road of pain and suffering. And if you do look at anything in the GUI display, don't compare it to what you see in Resolve.
The Clean Feed can be perfectly adequate if you're only editing in Resolve and don't need to make any precise color judgements on the fullscreen preview display. If you do need to see accurate color, you really need a color-managed output with a Blackmagic display device, plus a calibrated display. And to calibrate it, you need proper test signals, probes, and software outside of Resolve to ensure that it meets normal industry standards.
Steve Shaw of LightIllusion has a good essay on the importance of using grading displays for judging color:
