Some problems with profiling of monitor Dell U2713H

 I have bought the monitor Dell U2713H.

I can not find many answers for profiling it. Dell company has not any instruction about it - so I think that is it very bad.

For example, I'm interested in the following questions:

I create profiles with "Dell UltraSharp Calibration Solution" and i1Display Pro.

Record they to the LUT-monitor directly or LUT-video card?

Now I have made 4 profiles but it is not clear, which profile using in which color Space mode CAL1 oder CAL2 of my monitor?

For example. I have made one profile with sRGB color space, but I have not see it in any mode CAL1 oder CAL2 in all.
