Of course Shanghai is not yet developed.
Shanghai restarted developing in 1992, its impossible to get rid of all these old buildings within just a bit over 10 years. You can even see the same thing in downtown Manhattan. To be developed, it has to meet either two:
1. The whole nation becomes developed or at least closes to developed
2. All Chinese cities become developed.
The last two pics you posted Jiading & Nanhui, they are more than 30 miles/48 kms away from the city.
