Does removing this change our behavior w.r.t. the color setting users see when
the second time they print?

Yes it does :(. Not removing it, will default to a last user color instead of
default color setting for the printer (even for the new printer). This should be
addressed by a new settings code from Print Preview, that will store settings
for default printer only.

-  if (GetStickySettings()->color_model() != printing::UNKNOWN_COLOR_MODEL) {
-    settings->SetBoolean(
-        printing::kSettingSetColorAsDefault,
-        printing::isColorModelSelected(
-            GetStickySettings()->color_model()));
-  }
