Calibrate P2715Q Question

Using Datacolor's Spyder 5+ Elite, part of their "pre-initiation" checklist for calibration, they state to 1) set contrast to default setting and 2) set the Color Temp to 6500K. I don't see anything in the Dell software or the OSD option that allows setting contrast to default - just what the current setting is and the user can adjust it. Should it be taken to 100% or 50% or what?  Likewise, I could not find any color temp setting anywhere (unlike the LG that the Dell replaced). Do I simply chose the "Standard" setting if set on something else, as there is no indication on what color temperature or other dynamics those profiles are based on.  Thanks
