Do raster pyramids affect the values returned by the identify tool or popups?

Mark_Johnson

If you query a raster dataset, say a DEM, using Arc Pro's Explore tool or just clicking in a web map if the raster has been published, and the raster has pyramids, will the tool return the actual value of whatever cell is at the coordinate clicked, or will it return the interpolated value of whatever pyramid level the display is at?

The tool should return the actual service pixel value when set to display visible layers, provided the source files are visible.  The screen shot below shows imagery from our published service it returns the same value for both the original image and the displayed files files.  Pyramids are only used for rendering and not data; however, do watch out for overview files.  These will be different and are identifiable in the Pop-up info.
