What is dlLastImageFilename?

This read-only DisplayString reports the filename of the last firmware image successfully loaded into memory. An administrator checks this after a firmware update to confirm exactly which image file was actually applied. For example, after a download operation, the admin reads this object to verify it matches the intended new firmware filename rather than an older or unexpected image.
