The clutter of "fine art" only increased on the premises after the RPD moved in as Chief Irons had been taking bribes from Umbrella for years and funding his personal art habit with those gains, thus leading to his collection overtaking the station. They do a lot of neat rationalizations of environmental design through him, like the scattered, confused dispersal of weapons and supplies around the station also being the direct result of his orders, as he'd planned to sabotage the survival efforts of his staff for his own murderous entertainment as the outbreak was spinning out of control and giving him the opportunity to kill without repercussions. It's about as solidly conceived as anything in the series is in narratively justifying its own concepts.
