I agree but I think this a more recent development. Specifically as ISIS has been driven out of a number of oil fields in the North of Iraq and lost that oil as a source of funding.
I think the "idolatry smashing" propaganda videos are more selective now as ISIS needs to rely more on the sales of those artifacts for funding due the loss of the oil.
