FileVault Encryption Type Unknown

Hi Apple Community,

If a macOS Device is FileVault Encrypted, We are using the keys FDE_HasInstitutionalRecoveryKey, FDE_HasPersonalRecoveryKey from SecurityInfo to know the Device Encryption Type. But Some times rarely we get FDE_Enabled as true but both the above mentioned keys as false

Also we get SecurityInfo Response patterns like these only if FileVault is enabled in Device with iCloud as option to unlock the disk

Can we confirm this pattern or is there any way to know if device is encrypted with options other than Personal / Institutional Types
