LUTs look up a resulting value for each input value. If hardware wants 
to output 10-bit it can not use a 8-bit table as only 256 output values 
would be available. 10-bit in- and output requires 1024 table entries at 
least.
As a typical use case the LUTs should be able to pass through each value 
unaltered. If that is not possible the LUT is a limiting factor.

Btw. this is very basic stuff and should be covered in according IT 
learning material.

kind regards
