The "model" key is intented to show the model name - LCD2690WUXi in your 
case above.
However putting your complete string above into "comment" would be fine.
The later string shall lead to the final profile selection in UI´s.

The manual selection scheme is:
"manufacturer" > "model" > "comment"

The automatic scheme will reduce this to select from "comment" only.

The prefix of display_device is duplicated. Please consider a prefix like 
"OSD_" instead => OSD_settings_saturation_green .

It would be great to collect these infos automatic and not need to hand 
edit them. That would bring users he advantage they have already through 
EDID keywords. But that will need some time to come. Otherwise surely 
helpful information.
