There is no display resolution "where the text display is 100% indistinguishable to average human with 20/20 vision from a regular paper book." In fact, display resolution is not the most important factor in producing text as legible as a paper book. Notice I used legible, not indistinguishable.

Start by reading Wikipedia on font rasterization. Compare that to offset printing, the process that is used to produce most printed books. In offset printing, the quality of the paper affects how much the ink spreads as it is absorbed into the paper. There's no way to duplicate that effect in a digital display.

The perceived quality of text display on digital devices is affected by the font rendering technology (i.e. Freetype, Microsoft renderer, Adobe's, etc.), the text rendering technology (usually either an HTML/CSS engine like WebKit or a PDF renderer), the particular font, and the type of display (LCD, eInk, etc.). If all the other factors are executed correctly, the display resolution is only important at smaller type sizes. However, higher display resolution are almost always better because they give the various rendering technologies more resources to use.
