That’s good advice and Glen’s document above spells things out pretty clearly… ironically on the display profile I never trust the OS and software. I want to implicitly specify the one I want to use. I use windows so I copied mine to the color\out directory so I can specify the exact profile by name.
I am hoping Santa brings me a calibrator for XMAS 
Since I could not calibrate my monitor I always thought best to use the exact profile. However some of those profiles mess a bit with the gamma curve to handle blacks and so when you export in sRGB its not as close as you would like…I found out that actually setting my display profile to DT’s sRGB actually matched my screen/export better than using my display profile…
So I went this route for sometime. I did try the windows screen calibrator just for fun but I wasn’t entirely happy with it…
I am as a stop gap using calibrize now ( https://www.calibrize.com/ ) …simple screen calibrator that will tweak your system profile…make a copy with adjustments and set it as the system…it automates it and you can using the instructions you provided go back and ditch it if you don’t like the results…but I found using it I get a pretty good match for now until Santa come through…
