Also a programmer here. 4k 39" TV with zero scaling is my main setup. It's lovely - I highly recommend it. With a tiling window manager, I can see lots of code, run my tests, keep an eye on the command line, have API docs open, all kinds of stuff. It's even more dramatic than going from 1 screen to 2, IMO. In a way it's going from 2 to 4 :D
