Eh, I'd just pass it off as UI designer laziness. I mean, I've done crappy UIs on occasions because it was more convenient for a non graphic designer like me. But having the nerve of saying it improve the user experience ? Naaaah.
There is a fine line between trimming excess effects in favor of a more unified look (aka "flat design", when done right) and outright being too lazy to put in any color/shading.

Yeah, whoever took even a 10 minutes course on UI design should know color is the easiest way for the brain to identify icons before even analyzing its shape. That's the first thing they teach you.
