The Measure Point command allows you to click in a point cloud to see the elevation. If you have coordinate scroll up then you can see the Surface Elevation at the selected point location when you click and the point elevation from the point cloud shows up on screen at the same time.

Does this help? While not a dynamic scrolling read out, it does do what you want at chosen locations and it does also report the points in the History log. If you want to see the surface but not select it using Measure Points, use Advanced View Filters to turn the surface selectable to Off, that way when you click with Measure Points it will select the point from the point cloud.
You can also run the RPS Command called Points to Cloud if you want to compare a number of "Ground Truth Points" with the Point Cloud to get a check on the deltas between the two based on the nearest point cloud points to the Ground Truth points.
