Getting the Display Version of the current computer with Powershell7 (I.E.: 22H2). But ReleaseId conflicts with DisplayVersion

I've read a bunch of threads on here about this and I want to get the Windows edition (22H2 for instance).

This is the code:

$ReleaseID = (Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion').ReleaseId$DisplayVersion = (Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion').DisplayVersion$ReleaseID$DisplayVersion

$ReleaseID outputs 2009
$DisplayVersion outputs 22H2

Why is $ReleaseID outputing 2009? What is this number?
