No.
There is no standard way to get such information. To my knowledge,
there isn't even a linux-specific/non-standard socket option.
How would you propose getting such information?
I used to retrieve that info by inspecting wireshark/tcpdump logs, where the size of the current TCP window size is annotated in the outgoing packets.
And if you had it, what would you do with it?
It is a useful information. I could use it to see the evolution of the window during a long-lived file-transfer for instance.
