I was able to burn the same file to a USB key and boot it without any issues so I don't think its a bad image.

Well I tried on 2 different PCs with different motherboards, 2 different usb devices on my side. Perhaps you can provide some instructions on how one might be able to boot it?

Also, did you burn it with rufus?

No, I just did dd to the USB key from MacOS.

Tried from Linux:

# dd if=netboot.xyz-efi.usb of=/dev/sdc
6144+0 records in
6144+0 records out
3145728 bytes (3.1 MB, 3.0 MiB) copied, 0.621104 s, 5.1 MB/s

Doesn't show up in boot list. If I turn CSM on, it shows up in legacy mode, but says the media is not bootable (naturally as it is trying to do legacy bios booting).

I just tried the non-uefi usb image and it boots fine (with CSM), although it doesn't recognise my network interface (Intel® 2.5GbE LAN chip).

My motherboard is the Gigabyte Z490 VISION G.

This shouldn't be closed. I am sure there is a problem with the UEFI USB image, unless I am doing something wrong to boot it, have to enable something on the motherboard to boot it, etc.

But all other UEFI-only linux images I try to boot work just fine. Again, I tried in 2 different motherboards.

Did you disable secureboot in your bios ? IPXE images will never have a valid UEFI sig. I am going to close this issue, feel free to reply though I will get pinged and will respond. I cannot replicate this on any of my 3 test machines.

I know that this issue is closed, but I'd just like to mention that I'm having the same problem as the OP. Other OSes work fine, but writing netboot.xyz to USB using dd results in a USB that appears to have the EFI partition when mounted but will not boot on two different PCs I've tried.
