I guess my question is, why was it explicitly set to FALSE before and now we set it to TRUE? 

Why was it set to `FALSE` before is unclear to me but if you see the code where the value is being retrieved in [BasicColorChooserUI](url), it fallbacks to `TRUE` if the property is not defined (Code was added as an initial load, no modification after that). That is the case in other LAFs where it is not defined and hence the "Preview" title is visible. So, I think it should be `TRUE` for GTK as well as we do have a `Preview` panel in UI.

I couldn't find any native app as such but there are no tests which failed due to this change.
