Visualization of LiDAR by sub-meter elevation

I am trying to use GM14.2 to visualize and manually identify road defects using terrestrial lidar. Unfortunately I can not find a shader to uniquely colorize sub meter variations in elevation. This process works perfectly in the free Mars Viewer.

I tried to create a custom shader which would work but is very labour intensive as I have to manually enter a color for each 0.1m change in least to the best of my knowledge.

The LAS files are loaded into a GMC and I have tried to view it by first return only but that doesn't help. I also tried some of the options discussed in

Please see Options for manually identifying road defects from Terrestrial Lidar - Geographic Information Systems Stack Exchange for an example comparing GM with Mars and other software.
