This theory (it seems to be only a theory) does match my subjective experience. I find it quicker to scan 10s of lines of code to find something with a light theme. However I find it easier to distinguish individual characters with a dark theme. So when trying to parse something like a line of jsx, it's better. Overall I prefer (and use) a light theme, but I will admit that dark themes look 1000x cooler.
