Two Databases using query store - one saves Paramerized Queries as literals in sys.query_store_sql_text , the other saves them as parameterized

Question

I have two test databases - AdventureWorks2012 and StackOverflow2010 on the same SQL Server:

Microsoft SQL Server 2019 (RTM-CU21) (KB5025808) - 15.0.4316.3 (X64) 
    Jun  1 2023 16:32:31 
    Copyright (C) 2019 Microsoft Corporation
    Developer Edition (64-bit) on Windows 10 Enterprise 10.0 <X64> (Build 19044: )

I enable Query Store on both databases like so:

USE [master]
GO
ALTER DATABASE [AdventureWorks2012] SET QUERY_STORE = ON
ALTER DATABASE [AdventureWorks2012] SET QUERY_STORE (OPERATION_MODE = READ_WRITE)
ALTER DATABASE [StackOverflow2010] SET QUERY_STORE = ON
ALTER DATABASE [StackOverflow2010] SET QUERY_STORE (OPERATION_MODE = READ_WRITE)

And run a query on each that is parameterized by simple parameterization:

USE AdventureWorks2012
UPDATE  Person.Person
SET     FirstName = 'John'
WHERE   LastName = 'Smith'
USE StackOverflow2010
UPDATE  Users
SET     DisplayName = 'John Smith'
WHERE   Location = 'United Kingdom'

The query plan confirms that they have been parameterized:

If I look into the query_store_query_text view, I can see that Stackoverflow2010 shows the query as parameterised and Adventureworks shows the query as a literal

USE AdventureWorks2012
SELECT * FROM sys.query_store_query_text WHERE query_sql_text LIKE '%Firstname%'
USE StackOverflow2010
SELECT * FROM sys.query_store_query_text WHERE query_sql_text LIKE '%DisplayName%'

Why does one database show the query as parameterised in sys.query_store_query_text and the other show the literal query?
