I mean, sure. I've got a high-dpi tablet (Surface Pro 3, GNOME 3.38, 2x scaling), and it's obviously noticeable that the tablet is higher resolution than, say, my 32-inch 1440p monitor. Honestly though, the difference is pretty minuscule in day-to-day use. I can't help but roll my eyes when I hear someone brag about the merits of hidpi when it's really just a cool novelty that reduces the number of windows I can keep onscreen at once.
