I think you have unreasonably high expectations of what a PC version should be compared to last gen. When we got those older ports of PS3/360 games, they did start using DX11 features for the PC version because DX9 is old as fuck now and if their engine allowed them to use DX11 stuff they often did. That made it so that the PC version did have a lot of extra graphical features compared to the DX9 console version.
But now both of the new consoles can also use all those effects (but perhaps scaled down a bit to keep the performance in check), so a PC version will not be that huge leap above consoles for a while tech-wise. But that's where the extra horsepower of the PC comes in and you can get higher resolution, more/better AA and in some cases higher quality effects and such. But overall it will still look fairly similar to the console version, just cleaner and run better.
There will probably not be a lot of PC only features in PC versions (apart from the Nvidia stuff) until we start seeing DX12 games and whatever new stuff that will introduce.
And you bring up 4K performance and make it sound like it should be easy for a high-end PC to run Ryse maxed out at 60FPS. For some of the most demanding games, you will have to settle with 1440p if you want to play a game maxed out or close to it at 60FPS even with the best GPU's available now. Then we get a few exceptions like Alien: Isolation that runs amazing. But that game is also just a bunch of hallways for the most part, so it is easier to make it run good than something with more open environments (doesn't change the fact that it is a great PC version and I wish all games ran that good).
And Ryse did get an SLI profile in the latest driver update released the other day, no idea how good it works though. The game also got an update that improved SLI/Crossfire performance.
You are comparing apples to oranges here really. As even you say, it's because the console version is limited by the hardware that the PC version looks so much better last gen. Ryse wasn't limited in that way and therefore they can't really add much more to the PC version to make it look so much better.

When I compare AVP, Tomb Raider, Sleeping Dogs, MAX Payne 3 from console to PC it's night and day because some of the DX10,DX11 features only available on PC that make good use of PC architecture. But when a game is built from the ground up in a closed platform instead of the other way around like Crytek's previous entry's I don't see the advantages.
