while you are probably right and this probably has no bearing on the 757, there can be a fairly large difference in the 777 LR and freighters. Due to shorter fuselage and rudder arm you normally don’t see speeds less than 140 and actually on the freighters that used to require ballast fuel at very low weights now they actually have ref increasing when below 155 tons( approximately) so you could be 20 plus knots faster than a 777-300 Er at same weight.....often leading to floating and hence having to fly it on to the runway.
when I say Boeing lands flat I am primarily comparing to MD-11 that had the nose up around 7 degrees on touchdown so for me it feels flat!
