A lot of people would say 40ms to 20ms input lag between monitors is really nothing. Say you take two online FPS players. They are both top of their game and react on average around 160ms. The guy that has the 20ms screen will always have a 20ms advantage over the 40ms screen guy, so on average his hits will be registered first. There is no way around that. So yes, being able to "perceive" these input lag differences can not be so clear cut, but they still definitely have an affect in high end gaming.
Someone always brings up "High Level Gaming" when talking about rank-and-file TV sets....none of these will be purpose built monitors, and unless your name is Thresh or whoever the hell is the reigning twitch-wrist king in FPS gaming, is your 20ms lag-variation really ruining your imaginary career in professional gaming? No, probably not. Let's assume if you are THAT serious about FPS reaction times, you've laughed off consoles and moved to a PC, keyboard and mouse and are likely playing on one of the new monitors that can sync up at 120hz so you never have to worry about your input devices being your problem....nor can you use them as your excuse, either
"if only my mouse was faster...I'd have got that guy". Uh-Huh.
Also, let's go into this with our eyes open, your rate of transmission to and from the server is not static. You can test out at 30ms ping to a server..and then 5 seconds later get a 45....then get a 60...then get a 15....all in the span of the time it takes to draw and release a breath, and I doubt people are hauling these panels to Lan Parties.
Having said all that (and honestly not trying to be a threadcrapper here) is the Vizio P series still the one to beat in terms of gaming performance on a 4K panel in the budget section? There are Toshibas and LG's in the same neighborhood, but I don't think the 2015 models are shipping for any companies yet.
