System76 employee here! We do have a number of HiDPI models.

Galago Pro (https://system76.com/laptops/galago) is probably our most popular, and its resolution is 3200×1800—not technically 4K, but the right resolution for that small of display.

Oryx Pro usually has a 4K HiDPI option, but it looks like it's currently sold out. Our WS models also have 4K options, but they're pretty specialized machines.
