No. What happens at times is that either an eject command from the command line, like:
eject -v /dev/$DEVICE
or right-clicking on the device and selecting eject will either: (1) cause the device to disappear from the desktop or (2) cause a little mark about the device icon to disappear or (3) cause whatever is displayed for the device to change, any one of these indicating ejection. With the command line, it will show like:
eject: '/dev/sdb' is a multipartition device
eject: SCSI cdrom eject command succeeded
if it works, and will display an error if not. In the GNOME desktop environment, the eject will either remove the device from the desktop or cause the display about the icon to change.
It might be the icon theme or whatever, but it probably is in how it manages the devices
