I don't know about studies, but I'm pretty sure there is a large difference between very high contrast edges (worst case: text rendered without anti-aliasing) and photos or even videos, where there usually aren't any high-contrast high-frequency edges (black pixel next to white pixel). Since anti-aliasing is standard in font rendering and pretty common in computer games, I don't think very high PPD content would often be noticable.

On the monitor I mentioned, this text is about 15-20 pixels tall mostly-white on mostly-black, and I can read it from ~4 feet away. (website says that is ~186 PPD)

  That makes sense. Given that the smallest legible fonts are around 5 pixels tall, that's 3-4x less PPD than your monitor offers at 4 feet, so you'd need ~46-62 PPD eyesight to be able to read the text. 20/20 at 60 would be more than sufficient.
