ArcGIS Server API Identify null value

I noticed something inconsistent with "null" value handling in ArcGIS Server.

While doing "Queries", null values are retrieved as null (see attachment). While doing Identifies, null values are retrieves as string : "Null" (see attachment)

These are examples of "Query" and "Identify" for the same data so you can notice the difference also illustrated in the attachment :

Identify :

Query :*&returnGeometry=true&maxAllowableOffset=&geometryPrecision=&outSR=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&returnDistinctValues=false&f=pjson


I couldn't find anything about this on the forum and documentation.
Please, can anyone provide explanations ? Thanks

Also "Identify" return field aliases instead of field names, which is not handy at all.
