Train the whole chest the way that feels best and get to a lower bodyfat and pray that you have good upper pecs. Not much revolutionary things you can do with lagging parts in this world. I have friends who tries to get these 'upper chests' but everybody's shape does not change much.
But think of it like this. If incline hits your chest better, they are therefore better for you upper as well and maximal growths may make upper appear better even though the chest grows as a whole.
Also, if you front delts get more work, it may create a separation between chest and delts which makes the upper seem more prominent. Who knows.
Need to think about all aspects and try stuff to find the best solution.
Ps. I think BigBobs is a sort of gimmick. Despite my serious reply
