A pilot I worked with wore medal ribbons that included the DFC. Why not, he’d earned it? Campaign medals, the GSM, these days the LSGC medal and Jubilee medals. Well, I suppose it’s down to the individual and their decision might tell you something about them. I also know a few who opt not to wear medals on any occasion..
As an aside, I once asked a USN colleague about his ribbons. He went through them all but omitted one of them. “What about that one? I asked” “Well” he said, “1965 was declared National Defense Year and everyone in the forces got the ribbon. It’’s called Alive in ‘65! “
