Since you did this by copying the rEFInd files over to a bootable NetBSD CD (or did you copy them to an installed NetBSD disk?)  the two CD aren’t configured the same way.  Neither CD has an MSDOS partition/wedge for EFI and I can’t find where the files for UEFI booting are on the NetBSD CD.  My understanding of UEFI is that the boot files must live in an MSDOS/FAT partition, though that doesn’t explain how or why the rEFInd CD boots on real HW via UEFI.

GNU has a program called Xorriso that is supposed to be able to
extract the relevant files from a CD and write the relevant files back
to a CD to make it bootable.

It may (or may not) help here. https://directory.fsf.org/wiki/Xorriso
