Las reviews de la edición USA (o de la edición alemana) no parecen coincidir con tu valoración de calidad de imagen de la edición española:
So much of Housebound takes place either at night or in dark interiors that the Blu-ray's deep blacks are essential to Johnstone's carefully designed scares, many of which depend on flickers of movement in deep shadow and one of which requires a total blackout. On the rare occasion when Kylie ventures outdoors in daytime, the sight of her black hair against a bright (but barely blue) sky is a shock to the senses. Detail throughout the image is excellent, and there's a lot to see in the dusty old house jammed with bric-a-brac from various sources, including Graeme's workshop and the classically creepy basement where almost anything might pop out of the shadows. Even more can be seen in several other weird locations that get visited during the course of the film but can't be identified here. Suffice it to say that everything is visible, even in the shadows.

Clarity/Detail: From the opening prologue to the closing shot of the film this Blu-ray is freakin’ gorgeous! Contrast and sharpness levels are natural and I didn’t notice any sign of postproduction tinkering. Granted, I’m sure there was, but it was done to enhance the overall look and not just to make it look shiny. No lens flares were harmed in the making of Housebound.
Depth: I love low light in real life and seeing a film that is also low-lit is a great thing. It makes the house look warm and inviting. The Blu-ray handles this in a superb and refined fashion. It’s a classy presentation.
Black Levels: The film takes place primarily at night, even the beginning of the film, and the darkness looked great. I did not notice any instance of crush or compression. The darkness levels win on this Blu-ray.
Color Reproduction: Housebound has a very muted palette and even more so indoors. I didn’t notice any banding or pixilation either. It’s a very limited rainbow but what you get is epic in terms of richness and vibrancy.
Flesh Tones: Flesh tones looked great and everyone appeared to be in healthful spirits. Pun intended.
Noise/Artifacts: Not a single artifact, debris, dirt speckle was found, and I know that they shot this on the digital side of things.

Bild: Dafür, dass der Film merklich günstig (mit einer alten Red Kamera) gedreht wurde, sieht „Housebound“ auf der Blu-ray klasse aus. Bildschärfe und Detaildarstellung sind trotz der dunklen Szenen immer auf hohem Niveau. Die gut eingestellten Kontraste und der satte Schwarzwert sorgen weiter für hohe Qualität. Die Farben sind ein wenig gefiltert und lassen die Figuren etwas kränklich und unnatürlich aussehen, was aber prima zum Film passt. Das Bild ist recht ruhig und sauber, ohne dabei nur ansatzweise einen sterilen Digitallook zu haben. Insgesamt ein wirklich schöner Transfer, der das Optimum aus seinen Möglichkeiten holt.
