We’ve released an update that includes the feature I mentioned last month. If you go to the Settings ribbon, click Color Scale, click the Manual range checkbox, and enter a value in the Max field that is greater than the largest height value in your image, you will now see that the 3D view of your image is compressed along the Z (height/depth) axis. If you set a value less than the largest height value in your image in the Max field, the coloring of the image will change, but the 3D image will fill the 3D View grid box.
