That reports information about the kernel, no the world/user-space.
FreeBSD uname has a option that gives a clue about user-space ( -U
for the ABI version number ) but linux does not.

That is just about the linux kernel.

# more /etc/os-release 
PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye

# uname -a
Linux raspiOS64 6.1.19-v8+ #1637 SMP PREEMPT Tue Mar 14 11:11:47 GMT 2023 aarch64 GNU/Linux

I'll note that having 6.1.19 of the linux kernel is
far more recent than a standard Debian GNU/Linux 11
(bullseye) distribution . . .

https://distrowatch.com/table.php?distribution=debian

reports "11 bullseye" as having 5.10.46 for its standard
kernel.
