The original discussion was about changes to the show. The most recent bit was about “seven segment displays” of which there are several types.
Regarding the wheel display, it definently has the look of a vane display but compared visually to the display on, say, check-out, some differences are visible. For one thing, the unused segments of the display are quite invisible on camera, whereas the ones on the check-out display are quite visible. The color is also ever so slightly yellow, where vane displays tend to be very bright white. It also seems to change more instantly,where with vane displays you can sometimes see the folding and unfolding action, a long with the hinge mechanism. None of that is present on the wheel display.
If it is a vane display, though, it’s the best looking one on the set. Either way... interesting.
