Like with Blackpink’s achievement, this should represent real, organic views. YouTube stopped counting paid ad views toward 24-hour tallies in September 2019, reducing the chances that labels will artificially inflate figures.
This probably won’t end the quest for short-term YouTube domination. Labels like to brag about 24-hour view counts, and there will likely be more ways to drum up hype for a new music video. However, the achievement does show that YouTube still has plenty of room to grow — even if it’s limited to South Korean megastars.
