Here is the documentation of OCF what those Samsung devices are using:
I believe it is device2cloud, and then cloud2cloud as it mashed into the SmartThings API’s format, which obviously was not designed for it.
Meanwhile Samsung is the leader of Openconnectivity.org and develops both OCF standard and the SmartThings API. Basically the left hand doesn’t know what the right one does. So the end result is like when you have a square shaped body what you are trying to push through a circle shaped hole. You need to force it.
Just as an example this is part of the Dishwasher Operating State capability:
"dishwasherJobState": { "schema": { "type": "object", "properties": { "value": { "title": "DishwasherJobState", "type": "string", "enum": [ "airwash", "cooling", "drying", "finish", "preDrain", "prewash", "rinse", "spin", "unknown", "wash", "wrinklePrevent" ] } },
I repeat it once again, DISHWASHER! 
Of course, it is a proposed capability. For years…
