its not both, they make a CT one and a RGBW one, you notice that the range of CT on the RGBW is better that the CT one, this is because it uses the RGB LEDs to create the higher and lower CT. Hence why you see the RGB chips lit up.
yes, your just miss understanding it. It is a RGBW lamp which is RGB and tuneable white its just not a RGB + full CT lamp those don't exist to my knowledge.
the exact makeup of these lamps I don't know, but usually its RGB chips and a warm white (lets say 2500) and cool white chip (say 4500). The RGB does the RGB, the the CT chips give the CT range but on its own it can only do from 2500 (just the warm ON) to 4500 (just the cool on) but these lamps according to my states.
can do 1801 to 6535. So in order to do that the RGB part gets involved IE full RGB mix is usually a good "daylight white" 6500 so on that setting I would expect no CT chip to be on at all. where as 1801 is very red/ orange so it will likely have the warm white chip mixed with some orange from the RGB giving you the larger range.
If you look on their data sheets as I said before your notice the CT ONLY lamp has a MUCH smaller range because its fixed by the warm white kelvin chip and the cool white kelvin chip as its "high and low" limits.

I know they have done a few firmware updates to a lot of there lamps and I know there was one planed for the RGBW, maybe when this eventually gets released (might be already on their hub) it might improve this.
It has to have power...it should not need to be on (as in lit up). Mine weren't on when I switched drivers, but they turned on when the driver test was going on.
I found putting the device in a group for some reason helps it complete the test when it gets stuck. Send level and RGB changes though the group device and it often goes though, no idea why. YMMV though as I'm sure that would depend on the lamp or light fitting used.
