If you want a perfect profile for your monitor you'll need to calibrate it manually, using the profiler built into the OS is probably enough, but an actual hardware device that detects what the monitor can output is much better.
The OS can pull some colour information out of the monitor, but that's pretty much always wrong (I had one monitor claim White was Yellow), and as a fallback sRGB is pretty much the best you can hope for.
