Athlete Watch Face - Training Status 'F & L' Indicators?

On the marketing photos for the Athlete, the Training Status data field on the watch face (right dial) shows two trend indicators, F and L (presumably Fitness and Load) which I don't see on my Athlete, even now I've got 4+ weeks of activities on it.

Is this an option I haven't found yet, or just something that didn't make it into production?
