My guess is about a 3-4% improvement in overall energy system efficiency in hot countries.

Which is, as you say, not huge, but is pretty significant. Just on it's own it's a nice win. But you also get a benefit in developing countries of a reduction in the capital expenditure required to enjoy WEIRD standards of living.

There are roughly 100 large power stations in the UK (including currently operating, in planning or recently decommissioned), they cost about $500m each, so a 3-4% efficiency gain would avoid perhaps $2bn in capex. That is a goodly sum of money that places like Kenya don't have to find and a goodly number of Indian coal miners not down a mine getting lung disease.
