If that were the only line about Harry finding her attractive, then I would take your point. However there are many examples throughout the first five book where he finds her attractive, some of which I wrote in that link. And let's be honest, the "glowing like the setting sun" sounds much more romantic than the quote you posted from OP.

And no, he may not show romantic interest in Ginny until HBP, but he does show interest in her.
