It would matter if the quality of the two different cap had different sounds, matched Cap specs don't always predict matched sound. I read of people using "better" sounding caps to modify their amps while adhering closely to the original specs. I have even heard of Capacitor comparison shootouts.
In this case if you couldn't hear a difference, then the two cap types have comparably close sonics by definition (to your ears anyway). Thus they are nothing to worry about. If you have an open or see through cover then aesthetically it may matter to you, and many of us want gear that looks good and sounds good too.
