Yes, that may well turn out to be the answer.
I don't pretend to be a Viscount expert (I've only worked on, and flown on, the 800 series but not the earlier marks).
I've seen various references on the Net to wing incidence being 2°30' and also 1°30' - though that might simply be the washout difference between root and tip.
In any event, those photos look more like a 2-3° difference in the thrust line when comparing the 700 to the 800 IMHO.
I do know that the 800 had a different tailplane incidence, not that that helps.
