This is a no brainer if there is even the possibility of you upgrading you tv in the future and even if you don't. The developers can use the extra power however they see fit whether to thbat is 4K support, improved textures and/or frame rate improvements. As you can see in the screen shot I took from Tomb Raider There are 3 differnet graphical enhancements to choose from, and only one (in my opinion the least impressiv) requires a 4K tv. Also for you do decide to bite the bullet and upgrade one day it will be nice to have a console that can utalyze the technology you just spent so much on. In my option HDR makes a bigger difference than 4K
