I'm starting to guess it might be an in-game thing; can't really say for certain unless I look at it further. Under the video section of options at the main menu, is your graphics detail set to very high, anti-aliasing turned off, and texture detail set on high?
Put on a maximum and turned off smoothing, but near the mantle is not as clear as yours.The robe has many gleams and lines blurred when the character speaks to you and his face is close.
