If your GUI is scalable (we're talking physical display size not "resolution" here) independent of your screen resolution then yes, more PPI = "more crisp". It wouldn't be a gimmick or anything. More pixels you have to display one inch of screen, the more clear and crisp it becomes. Same thing like if you print a 72 dpi web image vs a 300 dpi print-ready image. The 300 dpi will be dramatically better. It's not about being "practical" (we can obviously get by with 100ppi just fine as is) its about advancing technology.
