Certain RAID implementations write metadata at the end of the disk and step on the backup GPT in this manner. But that was on computers with BIOS firmware that weren't GPT aware. UEFI firmware obviously should be GPT aware so it'd be quite a bungling if its firmware RAID were writing metadata where the backup GPT goes. But it's worth seeing if the firmware is up to date. You could also use dd and hexdump to read in ~100 of the last sectors of the disk, and see if the metadata written to that area is identifiable.
