Hi!
I am using arcpy.DefineOverviews_management() to define Mosaic Dataset Overviews, passing the parameters resampling_method='NEAREST' and compression_method='LZW', but these settings DO NOT take effect. When I later build the Overviews and open an image file in an image viewer, I find out that it has been generated with JPEG compression!
When I use the corresponding GP-Tool "Define Overviews" in the UI with the exact same parameters/settings, then my Overviews are generated with compression LZW as I wanted.
For the life of me, I cannot find out why this doesn't work when scripted...?
When I output GP-Messages from the script with arcpy.GetMessages() it even confirms that NEAREST and LZW have been passed as parameters.
Thanks for any help!

ArcMap or ArcGIS Pro? arcpy is not the same between the versions, so something may be amiss
It is arcpy with ArcGIS Desktop.
