More generally, visual simplicity will be penalized. As an example, http://jsbin.com/milelocito http://jsbin.com/milelocito gets a score of 0.011, and http://jsbin.com/fejevatihi http://jsbin.com/fejevatihi a score of 0.035. The site timed out while trying to calculate the scores, so I had to do it manually. The respective sizes were 3377 (html), 283130 (png) and 3323 (html), 92815 (png). This example is a bit contrived, but you'll see the same effect for more subtle decorations as well (e.g. box-shadow, ...).
