Point thinning and scalability of a LAS dataset—ArcGIS Pro | ArcGIS Desktop don't have one to test, but the process may not be exactly the same, but the limit is mentioned on this page
Thanks for sending this Dan. I have had a look at this before but can't find the setting I am looking for. I just want to remove this from the symbology so it will not show on the map. To achieve this I have transferred this to graphic and manually removed the text "Data Percentage:100".
