Psilocybin yes, ketamine no, DMT not sure. Compounds like those tryptamines are known for augmenting acuity but I'm really not sure it would last several days. It could also just be my subjective experience, the afterglow of mushrooms can really feel like my head is blasted open and a breeze of air can fly through and I can peacefully sigh.
Colors can also just seem softer even days after, but all of these things only ever so slightly. More like as an extension of the lingering 'awakened' feeling. But in actuality if you'd put me on the spot, it could actually turn out that I would be more immersed in daydreams so perhaps I would not function better because of better vision.
