The quantum to classical transition maybe caused by decoherence or by dynamical collapse of the wave-function. We propose quantum discord as a tool for comparing and contrasting the role of a collapse model (Continuous Spontaneous Localization) and various sources of decoherence (environmental and fundamental), for an experimentally demonstrated macroscopic entanglement. We discuss the experimental conditions under which the detection of either Continuous Spontaneous Localization or fundamental decoherence becomes possible.
