I don't have a solution to give you but I can give you a hint. This has to do with graphics modes. The "Vista green progress bar" is the fallback. Try playing around with boot flags/attributes in msconfig or bcdedit.
I tried revert back to original logo through bcdedit. It allegedly accepted but it didn't change the logo. Maybe it sees Vista bar as original logo? I wonder people who use Windows 7 as UEFI can actually see the original logo rather than Vista bar?
There is an app called Windows Logo Changer. I was going to use that to change Vista bar to original Windows 7's logo but the app itself doesn't support EFI/GPT. This is really not suprising as EFI/GPT systems are uncompatible with most of things.
I have a very new machine with UEFI running Windows 7. I have the proper Windows 7 logo at boot, not the Vista green loading bars.
What I said above, you are getting an automatic fallback due to lack of the proper video mode. You will need to play with the relevant boot flags for VGA. Otherwise your UEFI is not offering Windows the video mode it wants for the boot screen.
