That's probably because no one understands your question
I'll assume you use Cheat Engine 6.1+
The direct3d 9 hook does not modify Direct3DCreate9 , which is why you do not see a modification
That is has no effect in the game might be because you haven't given proper render commands

Keep in mind depending on your OS version as well, dxdiag does not use Direct3D9 to determine information. It will use the most recent version of Direct3D on your system for that.
Such as for Windows 7, you probably have Direct3D10 or 11, it will use those instead. So your hook for DX9 will do nothing.

I just looked at dxdiag on my Windows XP VM and it never loads d3d9.dll so it does not look like they ever create an actual device in the app to poll for data. If you need a Direct3D9 test application to work with, download one of the older Direct3D SDKs. There are a handful of example apps included with it.

From the look of it dxdiag on Windows XP doesn't load either d3d8 or d3d9. It polls all the data other ways instead.
As for testing on games that use DirectX 9, it is possibly your hook failing then. Or you are injecting it too late.
