To get a visual of the gamma, you can either select "gamma" in the pull down in the information box that's beneath the measures box, or simply click on the gamma graph - by default it's the third icon to the right of the continuous read button.
To see which gamma target you have active, you go Advanced->Preferences and click on the "References" tab.
You have it at the HCFR default for a pure BT.1886 gamma curve.
What @Dominic Chan
was pointing out is that your current curve isn't following BT.1886 even though that's what you have currently as the target. Your curve is pretty close to 2.2 power gamma at an average of 2.23.
If you'd like to adjust your gamma, you can change the options in Advanced->Preferences "Advanced" tab so that your "color difference formula" is CIE2000, though it could be any of the others, and that your "gray scale dE handling" is Absolute Y w/gamma.
See the attached picture - this is your gamma curve in yellow. The gamma target is changed to 2.2 and is orange - you can choose which gamma you'd like as I said above in the references option tab.
Ideally, the yellow and orange curve would overlap for a proper gamma.
If you did want to reach 2.2 gamma, you'd need to increase your red, green and blue from 10% up to 70%, and reduce your red, green and blue at 80% and 90%.
It's more important that your reading follows a gamma, any gamma, rather than be a random curve. So you could choose 2.22, 2.3, 2.4 whatever suits you, but just make sure that you are tracking properly.
Hope that makes sense.
Good luck and have fun.
