It gets worse. We want to know the visible area. On NTSC, the vertical blanking interval is approximately 22 lines per field. My reading of the FCC standard is that that should remain the same for color relative to the line frequency. So 262 becomes 240p, and 202 becomes 180p. Technically, it could get even worse. Vertical overscan is a thing; the Apple ][ places only 192 lines under computer control. But let’s stick with 180 horizontal lines. Here’s a size comparison on the vertical axis, ignore the horizontal.
An upgrade to Find My -- The AirPods Pro 3 includes an upgraded Ultrawideband chip (U2) that Apple claims increases the finding distance of the charging case by about 50% using the Find My app. I'm not sure about the 50% increase, but I did have fun trying to find AirPods Pro 3 with FindMy and they did give off a signal that the FindMy app noticed a little farther away than AirPods Pro 2. The coolest part is that this is likely a signal that a new second-generation AirTag powered by the U2 chip will also be coming soon.
