Interesting. I had not seen that before. I see it is new in R2016b.

The color thresholder app on the apps tab will show you the color gamut, which is the real name for what you're asking for.

You can also use the 3D Color Inspector plugin for ImageJ:
You can change color spaces and show appearance weighted by frequency if you want. You can also quantize into fewer colors, like as if you had run rgb2ind() on the image.
