You should be extremely skeptical of any taste comparisions that are not blinded. One recent story carried out a blind taste comparison of Walmart and Whole Foods produce and found Walmart was preferred for some items. If the taste test had not been conducted blind you would likely have seen very different results.
This comparison doesn’t directly bear on your theory since both the Walmart and Whole Foods produce was local and organic in most cases but perceptions of the source are very significant in taste judgements.
