We could use double precision (16 bits per channel) for first pass. That requires more memory for intermediate result, but it can be compensated by interleaving convolve operations over circular buffer. See chromium skia sources for details (refs in readme).
Also, it's possible to use double precision to pass data for unsharp function (but only if [1] done).

I don't know if it's really needed. But if someone find it funny - do it.

Will ot help much since JS has no access to gamma correction info. Only manual parser of binary data can help.
