I find myself sometimes wincing when I turn a page in a bike magazine to be confronted with a photo of something with hardly any spokes and a thick plastic - sorry, carbon frame. I think it's partly because the fat tubes and deep rims mean that the garish decals can be larger and more garish, so naturally they usually are.
In the days of lugged steel frames, the thinner tubes and flat profile rims necessarily had smaller, subtler decorations.
(Owner of a Spa Tour, which while modern(ish) is steel, is black with tiny gold logos. While it's welded together, it does have a gusset which you could pretend was a lug at the head-to-down tube joint).
