U2715H Preset modes, which one is most color accurate?

On my desk i have a U2715H monitor, and while i like it a lot, i noticed that there is a big difference in how color and brightness in handled in the different preset modes.

For content creation i want my monitor to be as accurate as possible,
However i noticed that the monitor has various preset modes:

Standard, Multimedia, Movie, Game, Paper, Colortemp, and Custom.

Currently i am doubting between Standard and Colortemp at 6500k
One thing i noticed however that in Standard that shadows seem to be a lot brighter and colors seem to be a lot more muted compared to Colortemp @6500k 

So which profile can i trust when i am doing color important stuff like colorgrading photos in lightroom or creating video renders?

Is the Standard mode more accurate, or is the colortemp 6500 mode the one that's correct? 
I also downloaded the icm for the U2715H though im not sure for which preset it is callibrated.

If its "standard" it would mean i would have to darken and saturate my images.
while if Colortemperature is the correct one i would have to lighten and desaturate my images.
