I live in an old warehouse converted into apartments. The walls are made of yellow brick and they're nice to look at because of the variation in texture/wear/color

Is this fair game? Looking at the details of the texture? Or wall here means "something plain, without characteristics".

Good point

Honestly, looking at this photo even for one second only triggers intrusive thoughts about how badly it needs to be corrected for distortion...

But maybe that's exactly the lesson.
