For whatever reason our kid's HS has had a bunch of NK asylum seekers lecture the student body over the years. We do have a massive Korean population here in western Fairfax county, VA. The stories he's heard from these people are remarkable. My wife got me a very interesting novel "The Orphanmaster's Son" which described the bizonkers system.
For a while I had access to North Korean TV in one of my jobs. Very little joy in those broadcasts. Their soap operas were all about struggle and serving nobly and at great sacrifice, the Juche state. Everyone was in uniform. Meanwhile, Cuban TV was delightfully latin: music, baseball, very attractive ladies in the soap operas.
I have heard that the excesses of the Russian "illegals" programs are dwarfed by what North Koreans do to their people. I cannot give details.
Basically...North Korea is a weird, weird place.
