If you run LO on the Mac as a service with --headless and you open a doc from a script with 
"Hidden=True", no window will pop up. If the document is open long enough (for example if you put a 
sleep in the script) you can see from the doc that there is an invisible window. From the Dock you 
can open that window. It does have the document filename as title, but it doesn't contain the 
document. It is a kind of strange window. Here is a script that extracts the text from a Writer 
document. Start LO as
/Applications/LibreOffice.app/Contents/MacOS/soffice 
'--accept=socket,host=localhost,port=2002;urp;StarOffice.Servicemanager' --headless 

and run the script with LO's Python:

import uno
from unohelper import systemPathToFileUrl
from com.sun.star.beans import PropertyValue
from os.path import realpath

localContext = uno.getComponentContext()
resolver = 
localContext.ServiceManager.createInstanceWithContext("com.sun.star.bridge.UnoUrlResolver", 
localContext)
context = resolver.resolve("uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext")
desktop = context.ServiceManager.createInstanceWithContext("com.sun.star.frame.Desktop", context)

loadURL = systemPathToFileUrl(realpath("test.odt"))
inProps = PropertyValue( "Hidden" , -1 , True, 0 ), # 1-tuple!

textdoc = desktop.loadComponentFromURL(loadURL, "_blank", 0, inProps);
print(textdoc.Text.String)

textdoc.close(True)
