All that is probably truth (even if serfdom was a thing until 1861 and so late like 1915 they were still dealing with the consequences), but there is a clear historical fact, whatever the soviet propaganda said: people well feed and happy don't start communist revolutions.
You mention Germany. The Bismark government (hardly a communist government) created the first social security program, probably because they were afraid of what could happen if they don't.
Yes there are lots of parallels to Germany, which also took a very state-driven development line in general, and this intensified during the war. I think Lenin's model was explicitly that of WWI germany. Of course the Prussian PR machine didn't sound much like the soviet one, but they were hardly polar opposites.
And the people eating the 1913 harvest didn't start a revolution. The empire fell apart after years of war (as did the Austrians, and the Turks) and then many factions duked it out. And then reconquered all the hungry people who hoped they'd seen the last of guys from Moscow, with guns.

I don't think it's so simple. We have to account for the revolution in 1905. The Wikipedia article is a good one (1) and I think it shows the zeitgeist. In my view is the pressure of the system in the peasants and in the proletariat what creates the conditions for 1917, even if the wars were the trigger.
