Yes, well that test puts it to rest then. 4x5 is unlikely to offer any significant resolution advantage. Although, I do think there is an advantage evident in another of Tim Parkin's tests:
Comparing the 4x5 Provia & IQ180, the digital sensor detail degrades into a blue and yellow maze of perpendicular artefacts as the lines converge, where the film degrades more gracefully (in my opinion). The digital image (in this test) appears to produce an image that is not faithful.
It's reasonable to suggest that the graceful loss of detail on film offers a not-trivial advantage in high-contrast detailed scenes (especially high-resolution black and white films). In overcast low-contrast scenes digital clearly produces better detail.
Perhaps this maze-like tendency of some digital sensors is why people look at their film and think it's sharper or provides more detail.
It would be interesting to see a test of current 150mp sensors, perhaps this has been corrected and the advantage disappears, but maybe digital artefacts like the blue-yellow maze are just moved further right.
