Good find, but aren't neonatal deaths are a subpopulation of the overall infant mortality stats, so there is unfortunately, still no clarity. Canada it was noted had similar pre-term birth rate as America (and presumeably higher than Austria and Finland).

It's like a grim logic puzzle where one gets a pile of facts and try to discern the answer.

Country A has higher infant mortality rate than country B. Country A has higher preterm birth rate than country C. Country B has a higher neonatal death rate than country A. etc..
