I think when it comes to "super recognizers," their fusiform face area (FFA) in the temporal cortex of the brain may be better/differently connected. The opposite end of this spectrum is prosopagnosia, where you can't remember any face. There is also prosopometamorphosia, where you perceive faces to be wildly disproportionate and demon-like (google it). So these might not be necessarily correlated with IQ as much as they are related to specific neural pathways/circuitry. Same can be true for visualization of data. There are many autistic savants who can perform specifically remarkable feats, but this isn't really translated perfectly onto the IQ test. The IQ test is probably an imperfect measure of all types of intelligence, but for general intelligence, it provides some level of useful data, but I don't think you can say that data covers all different specific scenarios like those described, sometimes it certainly might. There are probably people who can score 150 on an IQ test, but are actually unable to do any productive creative activity meaningfully.
