2016 Ford F150 XLT Gear Ratio incorrect from factory?

Attachment 155106 I opened up a tune file for a 2016 F150 XLT 5.0, and the tune file under the speedometer section says it has a rear axle ratio of 3.31:1. The VIN and the axle code on the sticker on the driver side door jamb says L6 which is a 3.73:1 gear ratio...

Truck has 114500 miles on it, and drives fine, kind of confused here.

There is a drop down box (Use Final Ratio) in the speedo section that is likely set to 'learn from BCM'. The BCM will have the correct values in its calibration.
