Well no! It seems to confirm my believe that the Lectures are scripture.
As your information says
"Renamed the Doctrine and Covenants of the Church of the Latter Day Saints, the book was presented to, and accepted by, the members of the Church in an August 1835 conference as the word of God. The change in name to Doctrine and Covenants reflected a change in content. Unlike the Book of Commandments, which contained revelations only, the Doctrine and Covenants was divided into two parts. The new first part consisted of seven theological presentations now known as the Lectures on Faith but then titled "On the Doctrine of the Church of the Latter Day Saints."
So the Lectures seem to be the word of God.They were voted on by the church conference which I understand is a requirement to be judged as scripture, Whereas it took only six members of the council of twelve to remove them in 1921.
Also since this thread is about what the LDS teaches about Gods nature. People would probably still like to know if the God of the B.o.M. is also subject to the "revision clause" you seem to feel applies to the God of the Lectures. ie can the nature of God of the Book of Mormon change with later revelations.
What eventually becomes "scriptures" & "official doctrines," in the Mormon church is always subject to changes allowed by prophets & apostles that come along, and at times, clarify, or put an end to different ways things might have been done in the past. The church is not subjected to things set in stone, but believes in progressive revealed insights as modern prophets can change, or clarify what went before. Thus,
it's the current practice of the church that constitutes the interpretation of the scriptures. As is often the case, someone often comes along & attempts to hold Mormons to everything some leader, or some earlier program, or conference gathering did & voted on. Then, say, "Hey, this was said, or that was done by your earlier leaders & members, so why isn't done, or accepted now? The answer is:
The current pratice of the Church constitutes the interpretation of the scriptures. For example, all the scriptures & sayings of the prophets before Noah, didn't, or wouldn't have helped the people of Noah's day, they had to accept what Noah said & did, as it was spoken by God through Noah, the current prophet of his day. Same with today. When Jesus started teaching his current "word of God," many of his time were upset, thinking he was "destroying the prophets," when he was fulfilling them. Paul came along & announced changes too, to discontinue many things of the Mosaic laws, these changes were argued over at a council (Gal. 1-2, etc.) So, changes are allowed also, according to
Article of Faith 9: We believe all that God has revealed, All he reveals now, & that he will yet reveal many things pertaining to the kingdom of God in the future. (Not an exact quote, but that's the whole point). Line upon line, here a little, there a little, as Isaiah said.
Thus, if later developments have brought about changes from the Book of Commandments, to the later Doctrine & Covenants, & further explanations have brought new insights about the Godhead & their nature, or even about there being a family in heaven that includes a Heavenly Mother. Such things are to be expected as new light & knowledge comes from current & future Mormon Prophets & Apostles. Thus, we aren't troubled by such things about differences in doctrinal positions changing, as further insights are added to the bigger gospel picture.
