The proportions and positions of Dembele and Lewandowski are different so I don't think this can be compared because even though their goals on the field are the same, their tasks are different.
Dembele is a typical running player whose job is to mess up the opponent's defense in contrast to Lewandowski who is a targetman.
Now when Barcelona lose Dembele, it will actually be beneficial in my opinion considering that with a 100 million clause, this will be better for Barcelona's finances which are still disturbed. On the other hand, this could also give Xavi a good option to look for other attacking alternatives to make his squad more complex.
Of course and both of them play in different positions even though they are both on the front lines, problem is I am trying to straighten out the previous discussion that Dembele's move could affect the overall quality of Barcelona's play. These two players do have different tasks and it is true that as you said, that Lewandowski is the final target for finishing goals, while Dembele has the responsibility to build attacks through the wings and although he also scores goals often.Dembele is a typical running player whose job is to mess up the opponent's defense in contrast to Lewandowski who is a targetman.

Dembele's salary burden is too large amid Barcelona's unstable financial condition, so his departure to PSG can be a solution to minimize finances. In that position there is also Raphinha who can replace and his performance can also be said to have improved in the previous season, so it will not affect the sharpness of the attacks built by Barcelona players.
Although in the end this will make a difference, there are other things that are more worth it than that.
The 100 million release clause and the reduction in salary burden that will be quite a lot when Dembele leaves will give a good return to Barcelona so I think it is something that is worth it to do.
Barcelona still have a cash problem with the wage bill so when there is an opportunity to improve it would be a shame to let it go.
