Are you sure ? I have never seen the original NIV Study Bible Notes in Logos. It has been a long time complaint about them not being available to Logos users. The closest we had was the Concordia Study Bible Self-Study bible which was the original NIV Study Bible + Lutheran addtions. What we have had in the past is what Zondervan at first confusingly called the Zondervan NIV Study Bible but then renamed the NIV Biblical Theology Study Bible to avoid the confusion.

Logos promised "concordances" too, but it's only a search engine. So I come to expect very little for a very pricey product.

There was a Lutheran version of the original NIV Study Bible published in Logos years ago. (Concorrdia Self-Study Bible). But I don't recall seeing the original NIVSB here.
