The point is the valeu of pieces is always diferent
While we always give it the same score
Actualy the same kind of mistakes is made in bishop versus knight games
It depends so much on the pawnstructure , tactics,  mobilety, and place of the
kings.

That giving a higher valeu for 1 of them almost always is a mistake.
But some theoreticans used extreme forms to benifit one above the other

In the situation of two White bischops the rook is not able to chase the bishops
away when they are conected
While it could drive away the bishops when it would have one Black and one White
bischop there fore they deffend better
But this is of more importance in 2 knights versus two bischops end games.
when the conection of the knights is lost the bischops shall win when not it is
hard to say which side  benefits.
