Death World usually refers to an entire planet or, at the very least, country, with living conditions so extreme that going there is considered taking your own life into your own hands. It can cross over with Crapsack World, but Crapsack is usually a primary setting that's of godawful living conditions, where as a Death World is usually a place outside of the primary setting that has essentially fatal living conditions for everything that goes in them (except maybe the things that are native to that setting, and they are rarely human).

Cosmic Horror Story is a genre, and it's also called Lovecraftian Horror. The setting of a Cosmic Horror Story, unless it's Lovecraft Lite, will invariably be a Crapsack World, but of a specific variety; in this genre, life means nothing and the setting is more often than not haunted by eldritch abominations or other such forces that even trying to learn about them will drive a man insane.
