I am sorry to inform you that we don't completely understand anything at all. We barely understand the world and universe around us. To say that we completely understand anything is a fallacy. Also with the scientific method, nothing is set in stone as fact. Anything can change our understand at anytime.
What behavior of light have we observed that the standard model doesn't accurately model? Where is the standard model inaccurate regarding light?
Here is one that I know of. https://en.wikipedia.org/wiki/Sonoluminescence
I'm not saying we are inaccurate. But look at the history of physics, there will always come a time when a new theory trumps the old.
