Here are list of models supported by quirks server:
https://chromeosquirksserver-pa.googleapis.com/modellist/modellist.html

Yes, the first 2 icc files are already on Quirks server.

Heh. It looks like we only refer to the .bin files from boot-splash.conf:

    if [ -x /sbin/frecon ]; then
      frecon --daemon \
        --gamma /usr/share/color/bin/internal_display.bin \
        --clear 0xfffefefe $DEV_END_USER --frame-interval 25 \
        $BOOT_IMAGES
    else
      # Disable blinking cursor. Without this, a splash screen will show a
      # distinct cursor shape even when the cursor is set to none.
      echo 0 > /sys/devices/virtual/graphics/fbcon/cursor_blink

      ply-image --set-monitors \
        --gamma /usr/share/color/bin/internal_display.bin \
        --clear 0xfefefe --frame-interval 25 $BOOT_IMAGES
     fi

Which leads me to frecon's main.c:

  static const char * const command_help[] = {
  ...
          "The gamma table to apply. (unimplemented)",
  };

So I think these don't get used anymore... right?

I'll remove the preinstalled files and then assign to Greg to clean up chrome/browser/chromeos/display/quirks_manager_delegate_impl.cc. :-)

common-assets: Stop installing ICC profiles and gamma ramps.

ICC profiles get fetched from the Quirks server (and the
two that we were installing are present there), and gamma
ramps are unimplemented in frecon.

init: Stop setting gamma from boot-splash.

Remove the --gamma flag from our calls to frecon (which
doesn't implement it) and ply-image (which I don't think we
use anymore).

It doesn't work and we don't plan to use it.
