"Is Packaged for Distribution" - node always returns false

The node also returns false when packaged with “Shipping” and “For Distribution” in the ProjectSettings is checked.
Using UE 5.4.4.

Bug?

Still getting always “false” in 5.8.

Here´s a workaround (Not working in Standalone Game Mode) :
Use the node “Get Current level name”, disable “Remove prefix string” on it and check if it contains „UEDPIE_“.
