Very small differences: not more than one bit on each color channel, resulting in 2^3 = 8 colors in the difference. A rounding-off issue, not random, maybe a floating-point multiplication by 255 instead of 256.

Actually (I just checked) these TIFs are not identical to the SIDs: the differences are around high contrast areas on the greyscale channel. Maybe the TIF mage were filtered (smoothed)?

I would have not spent my time writing those Python scripts if I could know this hidden Voynich-Old earlier!I don't remember, it was a few years ago. More "hidden" (not really, the download directory listing is enabled) goodies: some re-shoots (I don't know what changed) and 600 dpi scans.
