Why do you assume that VCs don't know this rather than assume that the market creates forces which make them not care? I'd guess there is more money floating around than there are startups which meet all the metrics. Thus there's investment in riskier ventures (remember it doesn't matter if any startup succeeds as long as the fund comes out on top as a whole). Moreover startups which do have all these metrics may have many competing VCs which in turn lowers the return for the VC.
