Wacom Cintiq Pro 16 color settings?

Curious as to what profiles are working for others as I'm going a bit nuts trying to color calibrate this screen.

No matter what combination of Color Spaces or Contrast settings I just cannot get a reasonable baseline out of it. Reds and Greens are incredibly vibrant with red taking precedence in general and wrecking low percentage blacks. And the blues are atrocious. Cannot get that pure RGB, royal looking blue to occur under any circumstance. I get the closest on a Custom setup, the the blues are still very pale.

Also curious as to what other people's lower end values are looking like. The blacks almost appear crushed. Black is a pure black until your at about a RGB 11,11,11. Really terrible. Can't seem to lift those lower values.

Currently on MacOS Sierra running sRGB color profile through the OS. Am I missing something obvious? Or is this screen just that mediocre?

If you've used something like the Wacom Color Manager or a Spyder 5, have you been able to remedy the weak colors? It's so inaccurate I'm considering returning it.
