More precise rendering (floating point vs. integer math), correct rendering on frame edges, rendering in "linear light", bicubic subsampling.

If you play video in MPC-HC without SVP do you see any picture?

I'm not sure, how do I try that ?

Ок, приведите пример для этого видео:

in this case "dxva copy back" will use AMD's card since it's the only card in the system

if your initial question "is amd supports dxva decoding" - the answer is yes

I bet it'll use Intel's gpu

Video driver is detecting "video player" software, that's why you can't choose discrete graphics for "mpc-hc.exe" in NV Control Panel (and with AMD graphics too). Renaming "mpc-hc.exe" to "mpc-hc2.exe" fools the control panel BUT actual rendering is still done with Intel's card (it's easy to check with EVR renderer, just press Ctrl+J). Which means the video player detection is more intellectual than just checking .exe name.
May be in this case all OpenCL calls are routed by the driver to Intel's card too.

Interesting question is: if you turn on GPU acceleration in SVP and select NV card as a target - will you see any load of NV's GPU in some monitoring software?

I mean if nothing can make it render the video through NV card may be (may be!) OpenCL code (executed inside the very same video player process) is actually running on Intel's GPU too.

is the svp cant run on newer graphic cards?

Blame NVidia and/or Intel with their Optimus drivers

I personally don't have any issues on a laptop with AMD graphics

How can I check that?

Control panel -> Clock, Language and Region -> Region -> Administrative -> Language for non-Unicode programs
