I am not able to clearly understand how that is related  to bits/channel. 
Could you please explain this?

Are you implying the following..
Because there is no extra to data to play with in case of 8bit/channel, its 
good to do pre-scanning correction.
In case of 16bit/channel, there will be more data, so we can afford to waste 
data during post-scan correction; thus no need to do pre-scan adjustments.

Thanks
Ramesh
