"More recently scientists have started actually mapping out regions where dark matter is concentrated than - from gravitic perturbations " This is not evidence of Dark Matter - it's really just quantifying and classifying the perturbations and anomalies derivations in gravity that we see. Basically, more detail to the observation that 'galaxies are not rotating the way we think they should'. That doesn't validate Dark Matter, it just more deeply quantifies the unknown.
