I don't have ATC, but I can replace the #330's in the climate controls with blue, either bulbs, or LED's if available. I replaced the ones in the EVIC and the rear handles, as well.
They are 5 LED bulbs, with one pointing down, and 1 pointing each cardinal direction. Pretty bright, but not over the top. I got 10 shipped for 30.00 on ebay.
I not gonna assume anything. The only way I would think to test it is take out the cluster, and shine an LED flashlight through one of the holes. You should be able to tell if they used blue film that way.
