A simple answer is that they see neither.

What they think they see is actually a short snapshot of North Korean life with a red circle, a red arrow and a red caption text that says "North Korean propaganda here!!! -->", carefully drawn by their local propaganda.

Sanity check: I present you a country X, whose language you don't speak, and whose news you don't read day to day. I show you their politician saying something. Can you tell if that was propaganda? Substitute X from "North Korea" to a country you know nothing about and see how the answer changes.

Seems reasonable but it's not as if no one speaks Korean outside North Korea to verify what's being said.

People don't believe native speakers of their own language when they're told things that conflict with their political world view. Why would they trust someone who says "that's not an accurate translation" if that collides with their political opinions?

For any outsider telling me about North Korea, including South Koreans, I can't tell if I've been pranked with e.g. the South Korean version of The Onion, let alone something milder like I'm being told about this by someone who takes their version Breitbart more seriously than their version of The Wall Street Journal.

You can translate it yourself with automated tooling nowadays. You can ask a second opinion from a different Korean.
