Is dash clock supposed to dim?

I just replaced the radio on my 2010, and after I reassembled everything I noticed that all the dash lights dim with the dimmer switch except for the clock. The clock dims a bit when I turn on the lights, but doesn’t adjust up and down with the knob like all the other lights. Is this normal for a 2010 or did I mess something up?

 

Normal.

 

I think it's normal, my 2014 clock just dims with the headlights, panel dimmer knob doesn't change it.
