I think this would be the right time and place to shamelessly self-promote my "The Long Night Falls"
TL. It should comply with the parameters laid by the OP, since it is a plausible best-case scenario for the Axis, where the interwar discovery of the Libyan and Manchurian oilfields triggers an event chain which keeps the USA neutral, reinforces the Axis powers, and leads them to achieve efficient cooperation up to a decisive victory against Britain and the USSR.
However, as much as Axis powers grow powerful during and after the war (a helluva lot), they never "dominate the world" since the Western bloc of the North American Union, South America, India, and Britain grows to be always at least as powerful as them. Rather the Western bloc and the neo-Axis bloc are locked into a perpetual Cold War competition all the way to space colonization.
Sssh! Don't tell Eurofed that!
Well, TLNF is certainly dystopian in the sense that there is a truckload of genocides along the way, probably as many as it was realistically feasible to accomplish without a social collapse. And there is not going to be any retribution for them in the foreseeable future.
It is not, however, dystopian in the sense of neo-Axis society getting trapped into North Korea-like static hellhole totalitarianism. It keeps evolving and reforming over time in a PRC-like way and eventually becomes rather more liveable in its 80-years post-WWII lifespan.
