Just as a note, breakfast in the rest of Turkey is also similarly diverse and excellent :-) You'll notice that each region has its own small specialty additions of spices, jams, pastries, eggs, etc. And often different fruits and vegetables depending on what's seasonally available in the area. It's true that breakfast in Istanbul doesn't quite compare to breakfast on the beach or in the mountain with tomatoes and cucumbers picked freshly from the garden, but still, quite a great breakfast can be had in the city.
