Again from fading memory, I believe that the original formulas failed
to be perfectly smooth, which was completely irrelevant in 8-bit but
could be argued to be significant in 16-bit. I also would not be
surprised if some 16-bit sRGBs have a slightly wider gamut.
These tweaks would break the "alignment" of 8-bit sRGB with 16-bit sRGB.
