Clearly you are having issues within the ALS logic. Within the camera is a second sensor which meters the light the camera needs to work within. This same sensor is used to adjust the brightness of the keyboard backlight and screen if the model offered it.
The fact you state the image is washed out from what is expected is telling us the sensor is not working or the logic within the logic board is not accepting the input either due to a bad connection or the logic on the logic board has failed.
There is also a second system used in conjunction with ALS that’s the lid Hall sensor which senses the lids state opened or closed.
The fact you stated the closing and subsequent reopening of the lid won’t allow the keyboard backlight to re-enable also points in this direction too!

Using a rare earth magnet what happens when you slide it across the Hall sensor just underneath the uppercase palm area along the side. Where the magnet is located in the lid? Slide it slowly across the area, the display and keyboard backlight should flicker and then go out, if you back off they should stay lit.

If you have a spare logic board what happens when you slide it in? While that won’t get us deeper into which direction it should help in eliminating the issue as a camera and ALS sensor issue aiming us to the logic board.
