Are all 6S Solars also Pro?

When looking at the 'stock' 6S Solar editions, I notice that they are also all Pro editions. Said another way, there is no stock non-Pro Solar 6S model.

But when building a watch via the 'Your-Watch-Your-Way' interface, the "Pro" terminology is dropped when selecting a 6S Solar, and the price is (depending on the band) $100 _LESS_ the stock models.

This would seem to indicate that the custom Solar 6S models are specifically non-Pro (i.e. don't have the Pro features), but this also isn't really documented _anywhere_ on garmin.com.

Has anyone else noticed this? And/or if you've built yourself a 6S Solar 'Your-Watch-Your-Way' model, does it also include the Pro functionality? (And if so, what's that extra $100 for on the stock models?)
