Notebook color display?

I bought the MSI Prestige 15 and of course I want the colors to be as realistic as possible. I chose "Designer" for MSI True Color because, in contrast to sRGB, it seems very realistic to me. Now my question: is "Designer" the most realistic color representation? Or can that be done even better?

The only way to get the monitor is maximum true color by calibrating it with a color meter. Although the modern IPS monitors are already quite good, it is almost a must for lovers of color fidelity.
