This is basically normal for now, though I think they forgot to temporarily override the command in this driver to hide the new parameters. The color temperature capability command in 2.2.6 was extended to include additional parameters for level and transition time (both optional). The platform will show these by default, but they are hidden/overridden in most stock drivers since none of them have been updated yet. We've been told this should be addressed in 2.2.7. In the meantime, all should continue to work as before, when the command took only the single required parameter: the color temperature.
