As it is, I spend most of my time making full use of the 42" screen for work (I work remotely, at home, a good amount of the time). It's great being able to have multiple windows in a grid format available, and multiple visible tabs, as well.
Also, I don't exclusively play shooters (if anything, I've been playing more strategy and role-play games as of late). The massive real estate is a nice plus, especially in hybrid FPS/RPG games like Fallout 4.
At this point in the game, I'm definitely a casual gamer (a long way from my raiding days in WoW 8 years back).
I'd still definitely recommend a 4K TV for the casual/enthusiast gamer who simply wants a nice budget option for a nice resolution and massive real estate. Pro/hardcore gamers should look elsewhere -- there are plenty of good FreeSync/G-Sync monitors to be had.
