Solomon's temple, Latter-day temple...discuss!

In 1 Kings 9:1-3 we have the account of the Lord appearing to Solomon to accept the temple Solomon's people (and bondmen) had labored 7 years to build.

The Lord accepts the temple, and agrees that His "eyes and heart shall be there perpetually."

In Doctrine and Covenants 1:1-10, we have a similar account of the Lord appearing to temple-builders to accept their work. This time, it is to Joseph Smith and Oliver Cowdery that the Lord appears, to accept the first temple built since His gospel had been restored to the earth, at Kirtland, Ohio.

In the D&C account, we have much more detail of the appearance and physical nature of the Savior,

"His eyes were as a flame of fire; the hair of his head was white like the pure snow; his countenance shone above the brightness of the sun; and his voice was as the sound of the rushing of great waters, even the voice of Jehovah, saying:

 I am the first and the last; I am he who liveth, I am he who was slain; I am your advocate with the Father."

We are also given more information about how the Lord will bless His temple, and the conditions for some of those blessings:

"...I have accepted this house, and my name shall be here; and I will manifest myself to my people in mercy in this house. 

Yea, I will appear unto my servants, and speak unto them with mine own voice, if my people will keep my commandments, and do not pollute this holy house."

Why do we have so much more information from the D&C account?

Well, it's an eye-witness recording of what happened, for one. It's never been translated, re-translated, or been through counsels to be voted-on to be canonized. It's a prophet's first-hand account of what he saw, right after it transpired. I would imagine Solomon's actual experience was very similar to Joseph's.
