I think you are seeing the difference between sports press (which still has a modicum of professional detachment) and enthusiast press (which is advertising). It's the sports press that blew open the doping scandal, for example. If they were the enthusiast press they'd be telling you which treatment is each rider is doing and could it be the best one for YOU?
I could see them doing something but it wouldn't look like a road bike magazine video. I do see a place for it. TV loves canned segments they can show during boring parts of a live event. It's usually "he rose above the challenge of someone else having cancer" stuff like you see in the Olympics
