Volume encryption status - macos

Question

How it possible to determine encryption status of non APFS volume?
For root disk it possible to use fdesetup status.
For other APFS volumes it possible to extract from diskutil info -all and check field FileVault.
But when I create a new volume by using "Disk Utility" it allow me to create "Mac Os Extended (Journaled)" and encrypt it with AES 128 or 256 but.
How may I get encryption status via terminal for such type volumes?

Following on from your comment, you will need to provide more information if hdiutil does not work for you: macOS version, type of disk image, format of disk image, how you reading the result, etc. With those details someone maybe able to help you.
hdiutil has been tested on High Sierra and Catalina with two images, 128 which is encrypted with AES128, and 256 encrypted with AES256, both HFS+. The result on Catalina:
% hdiutil info

Both disks have image-encrypted : TRUE.
