We use vortex matter in type-II superconductors as a playground to study how different types ofdisorder affect the long wavelength density fluctuations of the system. We find that irrespective ofthe vortex-vortex interaction, in the case of samples with weak and dense point defects the systempresents the hidden order of hyperuniformity characterized by an algebraic suppression of densityfluctuations when increasing the system size. We also reveal that, on the contrary, for samples withplanar defects hyperuniformity is suppressed since density fluctuations have a tendency to unbound-edness on increasing the system size. Although some of these results were known from previousworks, this paper makes the fundamental discovery that the ability of planar disorder to suppresshyperuniformity grows on increasing the softness of the structure for more diluted systems.
