I ignore what the GUI numbers say and try to only regard the Waveform monitor, Vectorscope, and the calibrated color display. Those will tell you the truth. The GUI numbers are "fudged" a bit and not necessarily accurate.
It is possible with some scope systems (like Omniscope) to magnify the scope image and let you see a much closer look at what's being changed and why.
I also tell my students whenever possible to only use the Primary controls in "Bars" mode and to use a control surface like a Blackmagic Micro or Mini or perhaps a Tangent Ripple or Wave. Any control surface is far more precise and exacting than trying to change the controls by the numbers, using a mouse.

The Bars mode also gives you the ability to very quickly see what the relative balance of YRGB is in each mode (lift / gamma / gain), so you can understand color changes in context.
