Grub Background Image not Displayed in Grub Boot Menu

Hi,     I have the following default config file in /etc/default/grub, and I have issued the grub2-mkconfig command to update /boot/grub2/grub.cfg which confirms that it found the background image, and when I look at /boot/grub2/grub.cfg it contains the necessary command to load png support and contains the background-image command to load the referenced image file, but the background does not display when the grub menu does, what am I missing? I've had used the grub-customizer app, without doing any config changes, and it successfully load the image from the specifications in /etc/default/grub.
