Agreed, a white dash top would reflect terrible off the windshield and they probably realized this. On the steering wheel it makes sense that white wouldn't be the best color for the thing you touch every time you drive in a pickup truck.When I saw these, I noticed something wasn't matching up... and just noticed the OC interior has changed. The top of dash and steering wheel wrap used to be white as well. I checked with an old photo of a prototype vehicle I saw in Seattle in '19 and the configurator as it is today. Configurator aligns with your post, but I'm fairly certain this was altered.
Either way, a dark top of dash makes more sense in bright driving situations, so no real loss.
