There definitely is a way for synthetic children, as you discovered below
For type formats, you can simply set the format on the SBValue on an individual basis (SBValue::SetFormat)
As for summaries, no, there is no way, as that would be nonsensical (don’t like the summary? just don’t ask for it - but there’s no meaning to getting the summary of a value once you disabled its summary)

Do you have a reproduction case I can look at?
GetNonSyntheticValue() returning self is correct behavior if IsSynthetic() == False; but if there really is a synthetic provider attached to the object, IsSynthetic() should definitely return True
