It is minor. The appearance of an Andiriaan would matter more in a TOS faithful fan production than the name of the planet.Meh. This is such a minor and nearly irrelevant nitpick that I don't let it bother me. Either way - the people who worked on the shows and had every right to make the choice made the decision to use "Andoria."
Do you guys likewise get up in arms over the fact that Star Trek VI called it "Qo'nos" well after TNG established it was called "Kling" in "Heart of Glory" ? Or that DS9 called them "Bajorans" even though Picard called them "the Bajora" in "Ensign Ro" ?
Even Spock was a "Vulcanian" for a bit. Nobody seems to lose their shit over that.
In fairness the name of the Andorian planet was never referenced in TOS. The home star could be called Andor and the planet Andoria. Or the homestar could be something entirely different. We call our planet Earth rather than Sol III even though our home star is called Sol. We call ourselves Human even though SF aliens often refer to us a Earthers or Terrans. No one ever refers to us as Solians.
SF often takes this shortcut where the inhabitants of a planet have a name (as a species) derived from the name of the planet itself and/or the aliens' home star.
In all of televised Trek have we never heard the name of Vulcan's home star? Not that I recall. We only heard Spock refer to "the Vulcan sun." We accept that Vulcan applies to the name of the planet as well as referring to the inhabitants. And the practice has extended practically to every other race we've seen in Trek. But a touch of realism would try for something at least a bit more varied.
Maybe the name of the Tellerite home sun would translate to "That fucking bright thing in the sky"
