i just watched most of the tekken 6 video that you posted and compare it to your older previous video of tekken 8 and i still feel like tekken 8 still looks like polished ps3/xbox360 graphic and physic. sure tekken 8 has much higher polygons count, better texture, and runs in 4k60p compares to 720p60. but the shaders or the lighting isn't that much improve. so is the physics. they look very similar.
