I would say that yes, you are right. But I would also say that every type of question suffers from this problem.
It's related to the fastest gun in the west problem - answers that are easy to provide (For the answering party) and quickily provided that then get accepted 'block out' interest in providing answers to the question, because the question is already 'finished'. As a result, the question gets less attention and fewer upvotes are awarded to the asker/answerer.
This is compounded by the nature of Identification Questions - once the answer is provided, potential answerers see that the answer is already there, and move on without looking at or upvoting the answer/question. Where in a normal question the answerer might think they still have a chance to provide a unique answer to the question, for an Identification question there is usually only one 'correct' answer, so a casual observer would skip past it and not bother trying to answer at all.
I don't see this as a huge problem - asker and answerer are already rewarded with an accepted answer (the asker presumably is happy with their answer, which in itself should be a reward) and despite the lack of 'additional' upvotes, the question is resolved with no further input required It might reduce the reward for answering quickly, but that's the risk you run when you're quick to the draw.
