My EX9.7 has the black and white display. Comparing to the color one, I am actually liking the B&W display more; it's more subtle, less in your face!
I mirror battery percentage and ride range to Garmin, so I usually leave the TQ display on the Watt output. Having watched that video, I'm also glad that pressing the button toggles between screens and that there is no need for a double press.
