Inspiron 7737 color display versus XPS 15Z color display

I have recently replaced my XPS 15Z laptop with an Inspiron 7737.   The 7737 so far has been wonderful, with the one exception of how it displays colors compared to the 15Z.  The 15Z colors appear bolder and crisper to me.  There's nothing wrong with the 7737 colors, but I am wondering how I can get the 7737 to display colors closer to how the 15Z displays them.
