The ICC profile itself will not change but your print hardware will change over time. As the printer get used there is wear and tear and parts will need to be replaced, such as print heads, ink lines, etc. Parts critical to the operation of the printer that are replaced, and serviced, can affect the colour behaviour of the printer. After printer service, maintenance and/or repairs you should have a procedure for checking and validating your print colour quality. Checking and validating your print colour quality on a regular basis provides feedback whether you colour is within tolerance or if remedial action is required - such as re-calibration and maybe even re-profiling.
