How do we compare Dynamic Range and Color Depth on picture?

Basing on DXOmark.com's sensor ratings. We can measure the ISO of cameras through comparing images taken at 100 - 12800 or 25600 with each camera
But how do we compare Dynamic Range and Color Depth on picture?

You already mentioned DXOmark.com, their webpage has a thorough explanation of how they do it - DxOMark - Measurements

I personally don't think there is a diference, as digital cameras really do produce only numbers, but I can respect other opinions on that.
My non-numerical interpretation of dynamic range - how much you can brighten up shadows without nasty noise appearing, and how much you can recover highlights without flat detailless areas appearing (I use Lightroom so it's "Fill light" and "Recovery" respecively). There is no way to define "nasty noise" without going to numbers and mathematics, "flat detailless areas" are a bit easier, as you can visually identify them.
