No, this is a fake PARTUUID emulated by the Linux kernel and blkid from a MSDOS partition table (disk identifier + partition number).
Unless you have set up your GPT disk to have a *flagged* BIOS Boot partition, booting in bios-legacy will be a problem.
The lack of a BIOS boot partition only makes GRUB less reliable because it has to use blocklists to load its core image.
