Some specific *not-to-be-named-per-the-rules* household animals have much better night-sight than humans. So when they are in a brightly lit house looking out of a window at night, are they able to see? Or is it just the relative different in light levels (bight inside, dark outside) that creates the effect, and eyesight doesn’t play into it?

Think of it like stars. Live in a city, lots of light polution, you see fewer stars. Go to the country, less light polution, you see more stars. They were always there, but because the surrounding sky was brighter in the city, the stars blended in better, and you couldnt see them as well.
Eyesight will play into it as the more light from a source can be picked up by an eye, the more that eye can send to the brain as an image. So animals such as the one not mentioned in the post will be able to see more in that night time situation.
However, relative light levels still play a huge role here. If it is significantly darker outside than inside, the inside light will inundate their rods and cones the same as ours, and reduce how much they can observe from outside.
