If it's on the disk, why doesn't the image get removed when I erase all partitions? Does the firmware put it back?

If I'm understanding this correctly this isn't necessarily the very first logo that would appear but one that appears as the firmware starts to boot an OS from the EFI system partition. So technically installing your OS puts the original non-malicious logo there.

It does, but if it has compromised the BIOS before that, that won't get wiped.
