Niépce's house is now a museum and photography is not allowed inside, so unfortunately there is no modern photograph of the view from the window that I can find.

That said, on the website of the Harry Ransom Center, you can see a sketch done by the historian Helmut Gernsheim, who rediscovered the original plate in 1952 (it is now on exhibition at the Harry Ransom Center.) The image you linked is actually a pointillist painting by Gernsheim; the original plate is much more washed out.

In the video on that webpage you can also see a 3D reconstruction of the landscape being viewed. The video mentions that the exact view in the photograph no longer exists because the window it was taken from was later moved to build a chimney.
