arcpy.ExportTileCache_management() storage format not working

[CheyneHadley]

In the course of automating my processes, I noticed that the storage format "EXPLODED" parameter is not being honored in a stand alone python script.  Every time I run the tool, it always outputs ".bundle" files.  It is supposed to output a folder structure with many ".png" image files.

import arcpy

arcpy.ExportTileCache_management(
    "G:\GIS\Projects\Tile_Cache\GUI_packed_tile_cache\Map",
    "G:\GIS\Projects\Tile_Cache",
    "python_exploded_tile_cache",
    "TILE_CACHE",
    "EXPLODED", <----------DOES NOT WORK, seems to only use "COMPACT"/"COMPATV_V2"

This tool seems to work fine using the GUI in ArcGIS Pro.  This is ok, I guess, but my workflow involves many other steps, which are all automated in Python.

Using the exact same parameters and inputs, I have two different results:

Running the tool using the GUI in ArcGIS Pro, the output is correct:

However, using a stand alone python script, the tiles are not exploded.  Instead, they are still packed in a ".bundle" file.

Note: I've tried this with the input tile cached created with both the ArcGIS Pro GUI "Managed Tile Cache" tool and the stand alone "arcpy.ManageTileCache_management()" tool, which works as it's supposed to in both cases.
