The title is misleading. There are smaller similar sensors. From the actual PR:

Sony Electronics Announces the World's Smallest and Lightest[1]

[1] As a 3D LiDAR with a measurement range of 10m or more under sunny outdoor conditions (excluding modules), according to Sony research, as of April 2025

So the smallest within those constraints, not overall. The iPhone ones are smaller. (And I think they also use Sony receivers?)
