The difference being that with Korea, it would have already had a fusion booster, which even in early designs increased the yield by a factor of 20-100 (Edit: depending on which pure-fission generation you compare to).
Edit: Also, I feel we need some tests again that get recorded with modern equipment - the old footage seems like from another world. People should be able to see it in 8K and VR to get properly scared of them.

There is no footage of modern tests because they have been conducted underground since the 60s in order to reduce contamination of the biosphere.
