Korean Yugioh packs can in fact be weighed, also known as scaled.
8.79 grams to 8.84 grams marks a normal non holo pack.
8.93 grams and 8.94 grams marks a holo pack.
There are approximately 6 holo packs out of 40 packs in a Korean Yugioh booster box.
It’s just the way Korean Yugioh packs are made up. They only have 5 cards per pack and so don’t allow for the diversity of cards in each pack that English Yugioh packs have.
