Hey Benny!
I have it booting to 4k with a 32p font I created from terminus-font's ter-u32b.bdf since regular console-fonts won't work with grub2 efi boots. This works;
grub-mkfont -o /boot/efi/EFI/ZNVER2_NVME/test32.ttf ter-u32b.bdf
Now the /etc/default/grub looks like this;
-={ /etc/default/grub starts }=-
GRUB_DISABLE_LINUX_UUID=true
GRUB_DISABLE_LINUX_PARTUUID=false
GRUB_GFXMODE=auto
GRUB_GFXPAYLOAD_LINUX=keep
GRUB_TERMINAL_OUTPUT="gfxterm"
GRUB_FONT=/boot/efi/EFI/ZNVER2_NVME/test.ttf
-={ /etc/default/grub ends }=-
Running 'grub-mkconfig -o /boot/grub/grub.cfg' results in;
-={ /boot/grub/grub.cfg starts }=-

I also have an uefi for the sata interface and can successfully install to a hotswapped 2.5" SSD on my so-called file server and then pop it into the target system - ASRock 4X4-4000 Series for example - and boot it up. That is what I initially did in order to create the above ZNVER2_NVME. Note that in the above cfg there are no references to /dev/nvme0n1p2 where the rootfs is installed to. For cross-referencing here is the output of 'blkid' for the installed nvme disk;
-={ Output for 'blkid | grep /dev/nvme0n1 | sort' starts }=-

I can also do the above for the 2.5" SSD if you think there might be some help in that. It is DEFINETLY different and I think the nvme disks are handling uefi boots far better than sata. The switch from grub to the linux terminal isn't seamless as such but is far less noticable than not supplying a more or less matching sized console-font such as latarcyrheb-sun32 which is what I am deploying.
The boot penguins get displayed as part of the grub display just before the real terminal display kicks in.
Life is good,
Maurice
