I also wonder how much tire results vary from frame to frame, depending on how the tire interacts with the frame aerodynamics.

You are correct, like many data, a screenshot without context is meaningless. The thing which is interesting in the video (the screenshot in from), they clearly say they do not know why the larger race king is better than the cinturato H.
They mentioned the road setup with the 105 aero estimation for narrow tyres and then go toward the turbulence cleaning effect and give some hypothesis but the big thing they keep repeating is that they do not know why and they say they got lucky. The results are applicable to the race king but are not a general rule and they do not know why? hypothesis, results have to be analysed and V & Ved (until there is real financial interest into that, it s unlikely it will happen).
One of the thing Dylan mentioned in his videos is that Aero and rolling resistance are the thing to look for. So as many said, it is about selecting the tyre that will favour these rather than a short distance of mud...
