What causes human vision to be less sensitive to high frequency errors

I think it might just be due to our senses not really being needed to be attuned to such high frequencies (like hearing or smelling for example). Unlike other animals we can use a good amount of our senses but not to the degree they do, probably due to just not being as evolved or specialized in it. As a result, it allows us to get away with having somewhat "crude" graphics by comparison but we can now make it much more efficiently and simplistically.

You can also think about how being able to see high frequency details was probably not as important to survival as low frequency details, e.g. being able to see patterns on a leaf vs being able to tell that there is an animal in front of you.
