These are spells from the PHB arcane spell list, which I would not consider as information gathering.
All of these spells are informational gathering, however, some of them might gather the information from a different source than the Mind Blanked creature. If they do, then Mind Blank does not protect against them.

They enhance you, but do not give you any information. Sure, with the enhancement you are able to obtain information you might otherwise not be, but they do not just give you the information.
All of these spells directly give you the information. You see the invisible creature because See Invisible penetrates his invisibility in some manner (the manner being unknown to us). But you cannot say what that manner is.
What you are doing is creating a "sub class" of low level minor divination spells that are somehow special and can penetrate the defense of an 8th level Abjuration spell, even though they do not state that they do. If they would not bust through Nondetection (assuming failed save), why would they bust through Mind Blank automatically?

Anyways, I can only offer you the reasons why I think it should be that way, I cannot give you any proof, since the RAW does not say how the spell works. It only lists a qualifier with no explanation as to what that means.
I think that if Telepathic Bond was not perceived by you to be helpful as opposed to being harmful, we would not be having this discussion.
I see the phrase:
"as well as information gathering by divination spells or effects"
to be no different than:
"as well as deception by illusion spells or effects" or:
"as well as damage by evocation spells or effects"
Just because the sentence indicates a little about what the school of magic is all about, does not mean that the phrase can be used to somehow state that the school of magic now has sub-categories that are outside of the phrase.
"Mind Blank even foils limited wish, miracle, and wish when they are used in such a way as to affect the subject's mind or gain information about it."
This states that if you are using these super powerful spells to gain knowledge about the subject, they fail.
True Seeing can be used to find out that the polymorphed Halfling is really a Halfling, but Wish cannot???
