I'm happy to report that the USB stick I made today with
grub-mkrescue-sed.sh does boot alright on tested machines.
As a side note, the machine on wich I made it is a Manjaro that boots in
UEFI 64 mode, so for sure it's grub is UEFI-capable.
The HP tested machine has, AFAIK, no CSM "legacy" boot mode at all and I
believe it doesn't boot anything but UEFI.
That said, I don't have the machine on which I made the stick at hand
and I made the ISO image in a tmpfs, so...
But directly analyzing the USB stick I made, on another (Arch) machine
now gives :
