Paris Air Show was quite funny for that: you could see pilots the A350 and on the 787 take off as early and as steeply as possible. I remember seeing the pilot of the 787 progressively take off several meters earlier (possibly something like 20m).

Also, this video was not at Paris Air Show but somewhere near Seattle as far as I know. The ground is nothing like Paris nor near Paris nor continental France. It was also posted to youtube the day after the first take off of the 787 before this year's Paris Air Show: no way they had managed to make a proper video in only a few hours.

It's also important to keep in mind the planes are really empty when they do that: even the A380 manages to fare very well for such things. Now, add 600 people with luggage for a total weight of at least 100kg and add kerosene too: it'll be entirely different.
