Just to add to this, as I now had a time to go back and watch the broadcast... after the chequered flag, the overlay showed the following fuel usage for the top 10:
Hamilton: 99.22 kg
Rosberg: 99.46 kg
Bottas: 99.04 kg
Raikoennen: 99.42 kg
Vettel: 99.35 kg
Massa: 96.35 kg
Maldonado: 97.09 kg
Hulkenberg: 98.65 kg
Kvyat: 98.62 kg
Grojean: 97.56 kg
Given that the fuel limit per race is 100 kg, it's hard to explain how Hamilton was supposedly underfueled if he at that point used pretty much all that was allowed. If they were indeed underfueling cars, I would think it would need to be by at least a few kgs to make a meaningful difference, but as I also mentioned, I don't think Canada would be the race to do it.
What the above figures also show is that all these cars were pretty much fuel limited, so pretty much all of them were not driving to the limit of the car, but to the limit of the fuel to get to the end of the race. In that sense, it's hard to argue that Mercedes had "a lot" of untapped hidden potential it was hiding and just managing... Vettel also pretty much used all there was to be used, but he also had traffic which might have cost a little more fuel (but on the other hand, had slip-stream here and there, as well as DRS on a number of laps). In the end, we still get to wonder about the Ferrari's full potential on not fuel limited tracks, but the same also applies to Mercedes.
IMO - I think if Vettel had started on the 2nd row, it would have been close, but I still think both Mercedes would have prevailed. But being fuel limited would probably bring the gap closer among different cars, assuming both have a similar fuel efficiency...
On that note, Massa didn't seem to have used a lot of fuel. Perhaps he was underfueled slightly as a gamble?
Also on the topic of fuel management; I wonder how the teams find the best balance between saving fuel and showing pace. I would think if you save fuel at the beginning, the effect is bigger because you are on a heavier car (= more potential to save, so the gain later is bigger) and get to reap the reward later on when you can drive at a higher relative pace for the extra fuel you saved up. Do it the other way around and when the car is quickest, you are in fuel saving mode. So one over the other might yield a much better race-distance time in total... (speaking strictly on the thought behind getting quickest from lap 1 to lap 70 with X amount of fuel).
