Obtain the point cloud intensity of PhysX lidar

I check the sensor extensions ( Range Based Sensor Simulation [omni.isaac.range_sensor] — isaac_sim 2023.1.1-rc.8 documentation (nvidia.com)), find that the omni.isaac.range_sensor.LidarSensorInterface.get_intensity_data() can get the point cloud intensity, but the intensity value is either 255 or 0, it is because Physx lidar cannot output the reflection intensity of point clouds at all?
