MacBook Pro Touch Bar Not Lighting Up?

MacBook Pro Touch Bar has stopped lighting up.

The Touch Bar functionality is still responsive to touch, as is the touchid fingerprint button to the right of the Touch Bar, but the Touch Bar does NOT light up. You can tap right side of the touch bar to use the Siri function, or tap the other stock locations for volume mute, brightness adjustment, volume level change, etc.

Troubleshooting done.

- Checked All Keyboard Settings, Power Saver Settings, any Setting involving the keyboard, power, etc.

- Reset SMC, Reset PRAM, Reset NVRAM.

- Performed Restart then COMMAND+R Disk Utility, Formatted Hard Drive and Reinstalled macOS.

Still Not Lighting Up? MacBook has never had any physical damage or any malicious software.

Now formatted to new with most updated macOS High Sierra 10.13.5 ( done on June 10th, 2018 )

Any help would be very appreciated, laptop MSRP over $2000, after over a decade of loving Apple products, this is my first disappointment and unfortunately on the most expensive Apple product I have purchased to date.
