Your #nofilter photo is passing through a lens vastly different from your eye, with a different aperture, focal length, and field of view. The light is hitting a grid of colored detectors with a filter to avoid grid patterning where it's converted into electrical signals, collected, and turned into photo data by software that decides what intensities on each detector area should be converted into what digital pixel. Your camera might be collecting light for a microsecond or over a second. Your brain forms images through a lifetime of experiences.
#nofilter means that you simply accept your camera's physics, settings, and software for your final output. It's far from "No Filter".
