Does raster statistics improve drawing performance when drawn from javascript ImageServiceLayer?

I'm new with raster concept, so reason why I ask the question because when publish Image Service using arcpy, it shows

"Raster data source does not have statistics CODE 10010) and came across this:


10010: Raster data source does not have statistics—Documentation   (10.3 and 10.3.1) | ArcGIS for Server


and it said: "Your raster data source does not have statistics computed, which can degrade your raster display and potentially impact drawing performance."


My understanding is that statistics only needed if we want to do raster operation.


So if there is no operation on the raster (only display), do we need to calculate the statistics?

If raster has statistics, is it drawn faster when ArcGIS javascript call it from "ArcGISImageServiceLayer" API?
