I figure this as well. It is stated that the content is auto clipped to a circle for design uniformity. I display temperature in corner complications, using the gauge to show current temperature in daily min / max. The actual value cannot be determined from the gauge, and so displayed as curved text above the gauge. accessoryCorner's gauge's currentValueLabel can be specified, but I don't see it displayed. Displaying text in the circular area makes the content less glanceable
