In webUI you can see the profile install status, but in API you can only see "assigned" and no visibility of whether it installed or not. This is useful information, particularly in my case when assigning a SCEP profile where the CA is in corporate network. The profile install frequently fails due to devices being off LAN.
This could be an install status when querying device/profiles or an installed profile list when querying devices, which we'd compare to assigned profiles.
