Computer science typically doesn't teach many specific languages or SDKs, focusing instead on giving you the tools to be able to create your own implementations.
You should have a grounding in the theory and design of: operating systems, languages, data bases, data structures, algorithms, networking and some math. I feel that you may be focusing on specific languages and syntaxes instead of getting at what lies underneath and makes them work which is why you feel underwhelmed.
Look at it this way: give a man a fish and he eats for one day, give that man a computer science degree and he can design a multi-platform fishing simulation to feed the whole tribe. Or something like that, you get the idea.
