OK yes, it a literal sense you can see things that happen in less than 100ms. What I mean is that you can't tell whether the nominal amount of flicker on page load is from the time it takes to paint the DOM or from the network request. Unless you were asking a professional front end developer, I don't think most people would even have any intuition about what was happening.
