We know that the algorithms were improved for the Voyager series over the Spice. That the 41 has an improved algorithm also isn't a big surprise.

But the 41 came out earlier than the Spice, so this would indicate a defect in the HP-33's version of the algorithms, which was later corrected for the Voyager, no?

No, the Spice models (all but the 34C) came out more than year earlier than the 41, while the 34C came out at the same time as the 41, as a lower-cost alternative.
