and the facts that history and society in general now recognise the war as being an imperial dispute
No. they do not.

Prior to WW1 it was openly referred to as "The Great Imperial War"
Huh?!
- the museum commemorating it is titled The Imperial War Museum -

It was originally called "The National War Museum."
The name was changed to recognise the contribution of countries of the empire.

Prof Dr Gary Sheffield.
"Growing up in England in the 1960s and 1970s, I was influenced by what amounted to a "national perception" of the Great War as an utterly futile conflict, fought over trivial issues. It was only when I began serious reading as an undergraduate that I realized how wrong this idea was. In particular, I was struck by the views of German historian Fritz Fischer, who argued that Germany had gone to war in a bid for world power—the events of July 1914 were the occasion rather than the cause of the war. I simplify Fischer's arguments, of course, and I don't accept them in their entirety, but at the very least he pointed to an expansionist, militaristic tendency among German policy makers."
