Try rostopic echo /camera/depth/points .. if u seen data is being transferred then u might have to adjust some settings in rviz related to tf..

Can u elaborate problem with tf. Use tf_echo to check transformation between frame_id of camera_depth_points and constant frame like map/world or maybe odom. Are u seeing points when u echo /camera/depth/points??

Make sure you run $rosrun dynamic_reconfigure reconfigure_gui, select camera/driverfrom the list and tick the box for debth_registration. In rviz, change your PointCloud2 topic to/camera/depth_registered/points and also you will see color transformation below the topic, set it to rgb8. make sure your fixed frame is set to /camera_depth_optical_frame.
