What exactly is the customization in the example? Is it that the colorbar consists of a discrete selection of colors, or is it that it has tapered ends?

It's not clear whether the triangle bits are included in the colortable or not. It doesn't make sense that they would be, but either way, it doesn't make sense that one is white, and the other replicates the prior color in the table.

For all colors shown:

CT = [255 255 255; 
220 220; 
238 238; 
255 255; 
238 144; 
255 0; 
165 0; 
0 0; 
0 0; 
0 0]/255;

Excluding the ends:

CT = [220 220 220; 
238 238; 
255 255; 
238 144; 
255 0; 
165 0; 
0 0; 
0 0]/255;

Make of that what you will.

@Matt J, by customization I meant discreet colorbar using ticks as shown in example, and caliberating my data accoridng to these tick labels. I am not looking for the tapered ends, the example I have posted is generated in Python. Thanks so much for asking. I have found the solution though.

As suggested by @Dyuman Joshi, I digged a bit harder on the forum, and solution was there. I am posting the link of the solution here;
