It's not something that affects gameplay in practice because it's still possible to tell between the two, but it's still an inconsistency that two things that look different when unID'd then look like the same thing with different modifiers once ID'd. Maybe I have a somewhat OC type of personality but it has always bothered me.
If stuff like typos, British vs. American spelling, or "Chaos" being written in upper/lowercase in different messages are being fixed, I don't see why this shouldn't be fixed too, it's a much more significant inconsistency than those. And the fix would be as simply as setting the ID'd name of the bloody dagger to "bloody orcish dagger" or "refined orcish dagger", for example.
