Likewise DM priority bags will read Class: F
I don't think this is true in my (~50) observations as SL/GO. The "Class:" label always reads my fare bucket, which is usually M/K/R in my case. However, when I have been op-upped to J at check-in, the tag will read Class: J.
Maybe this has changed under the new check-in system?
