Detecting Characters

I have a SQL Server 2022 English default installation on a server. I want to detect if there are any upper case characters in rows and I have this code:

SELECT CustomerNameID,
       CustomerName

 WHERE CustomerName = LOWER(CustomerName)
Here is the sample data I am testing with:
CustomerNameID CustomerName
1              John Smith
2              Sarah Johnson
3              MICHAEL WILLIAMS
4              JENNIFER BROWN
