You’re assuming that monitors and printers can be trusted to accurately reproduce the colour space even if there was a profile attached (which, by the way, most monitors do actually have). This isn’t true. Particularly with monitors where people can adjust the contract and brightness. The reason colour profiles exist is so that computers can be calibrated to support the monitor output. You are also ignoring the fact that environmental factors can have an effect too. Ie how the room is lit. Comparing something standardised like writing glyphs with something highly individual (monitor calibration) doesn’t make a whole lot of sense.
