These numbers can get wonky fast. E.g. devs salaries in Ukraine are pegged to the dollar, so they get free raises as the exchange rates plummet. At the same time the cost of living in Ukraine was low before the war and only got lower. Oh and taxes are pretty low in Ukraine.
So I'm pretty sure Ukranian devs will end up with one of the top salary rates in all of Ukraine, but the externalities of that are large.
