The UEFI spec requires discrete ("plug-in") graphics devices to support at least either 800x600x32 or 640x480x32. And the edk2 (not just OVMF) default for the console resolution is 800x600.

But that's a less important feature. It's more complex than you might think, and (to me personally) it seems to require more time than its importance justifies. https://bugzilla.redhat.com/show_bug.cgi?id=1749250 Laszlo
