There is one exception for the boot-up animation if you have a domU where ATI card was installed.

I have a domU Win 7 64 which I use for my previous ATI tests.

After removing my ATI card and putting my GTX 680 back in  this domU I remove AMD driver and I installed NVIDIA driver.

When this domU is starting up the boot-up animation appears only in the VNC console. After that the animation is "frozen" on boot-up animation  in VNC and the Windows screen (login screen) appears in my physical monitor.

This domU above is a different domU than the 2 other domUs (Win XP 64 and Win 7 64) freshly installed.

Right. And since you aren't side-loading the GPU BIOS, I would guess
the boot-up animation doesn't appear at all. It runs headless right
up to the point where the GPU driver loads in Windows.
