Hi James,
So -- Those are the "identical" RGB values. If you decrease the overall panel brightness to be much lower "similar" levels to what your monitor is (we are talking about actual light emittance here not a "brightness number") you will find that the colours on the panel come down and will look similar. On the flip side of that if you crank up your display Brightness as high as it goes you will also see the GUI colours increase.
This is why Reference Monitors are expensive and you need to run a Colour Calibration Tool and software on a monitor so that what you see is what you get.
All of the Panels go through a Calibration Process where we use Cameras to take images and software to calibrate all of the LEDs on the panel modules -- that way they also match side by side. If we don't do this then you can see a huge difference in the colours on a button by button basis. So the Panel colour is correct. DashBoard is representing the colour on the panel to best of it's ability.
