Would it be the same font used by the bless command in Catalina to make the .disk_label_2x file?

}makemultilinedisklabel "/Volumes/ElCapitan/System/Library/CoreServices" "ElCapitan"$'\n'"10.11.6"Do TB add-in cards have option roms? The rom they do have is the firmware that runs in the Thunderbolt controller, and is probably not EFI code that runs on the computer's CPU?
There are two SPI flashes, I'm assuming that one is the TB controller firmware and the second is an option ROM, someone correct me please.
Has anyone dumped the other SPI flash? Looking at that might be the easiest way to see if it's a PCI option rom since PCI option roms need to follow a specific structure.
sudo lspci -nnvvvxxx > lspci.txt and search for Expansion ROM. But devices can hide their expansion rom.ioreg -flw0 > ioreg.txt and egrep for phys\.hi: [0-9A-F]{6}3[08] but devices that showed an expansion rom in lspci might not show it in ioreg.
I believe the bless command doesn't "use" any particular font, as it is just a terminal command, Finder shows the contents of the .disk_label_2x in whatever font it its supposed to display it in... Isn't the weight of the typeface too heavy for boot screen? I think Finder shows bold, and the boot screen uses regular.
The disk label is a 8 bit greyscale bit map. Use the dump_label command to show what it looks like.
3840x1080 is fine with my Radeon VII.
My own config is customised, which may not fit for your cMP.

You may try force the resolution to 3840x1080
