And we’d expect Ravenclaw members to already be using any clever potions or at least have rules against them (either imposed by the school or by themselves as ‘cheating’). In canon, they all know about the Ravenclaw diadem which is supposed to make you more clever. So it’s reasonable if there were any such thing, Harry would have been told about it (everyone knowing his interest in self-improvement or being more clever), heard of it, or read about it by now.
Who says he didn’t? I notice that Draco is unusually bright, as are Crabbe and Goyle. It would certainly be convenient for the Malfoys if the youngest sons of all three families were significantly above average....

Yes, because people want Harry Potter to be smarter than he is.
If it existed and was semi-public knowledge, then Lucius would have made a priority of acquiring some for Draco.

Draco doesn’t even need to know about this.
