lsblk vs blkid to fetch UUID

Hi,
I have a use case which involves imaging of a system using custom
scripts. Imaging involves installing an operating system and
formatting all the disks and setting up a File System.
At times I would like to enable LUKS on certain disk partitions, so I
format the partition using cryptsetup to setup luks format.
However, I had been seeing issues with fetching UUID post luksFormat
using lsblk.  I have seen the same issue with blkid but its
occurrences are exponentially less.
I want to use lsblk because its faster but seems like blkid is more
reliable here.
From what I understood from the code, blkid opens a FD for the device
and reads directly from super block; however, going through the code
of lsblk.c I see lsblk_device_get_properties() gets it from various
methods.

I am slightly confused as at that point in time the device database is
not set up so is lsblk fetching the UUID the same way as blkid does
using libblkid? Any information on this will be helpful.
Please correct me if my understanding is incorrect.
