Well, no, human eyes are way worse in low light compared to modern DSLR sensors. With a monochrome sensor you can get already exceed 50% quantum efficiency, requiring only a few hundred photons per pixel to get decent quality, and around 10000 in the bright spots to reasonably match what a TV can reproduce (dynamic range and perceived noise). But with a color sensor you can get recognizable/useful colors down to about 100 photons per pixel. Yes, it will be noisy, but at that light level (assuming a remotely-fast lens) your eyes will give you a hard time when you even try to read normal text. Should be enough to walk without tripping, though.
