Compass app GPS significant digits displayed

The Compass app in my iPhone 13 provides GPS Coordinates down to whole integer seconds of arc of latitude and longitude. Google Earth (and hand-held GPS units) provides much finer resolution (factor of 100) by providing the seconds of arc to two digits to the right of the decimal place. At my location in northern California, the distances on the ground reported by Google Earth corresponding to one second of arc are as follows: N-S = 100.29 ft; E-W 81.28 ft. I have read that recent iPhones have built-in technology (Assistive GPS) accurate down to less than 12-inches. Unfortunately, the default display resolution on the Apple Compass App is limited to one second of arc resulting in ambiguity at my location (assuming the internal data is finer but rounded) to, at best, half the distances reported above. Is there any way to increase the number of significant digits displayed in the Compass App?
