Reflections & glare are a couple things that really mess with filming, even in the lower-res TV (vs. movies) stuff of the time.
You'll notice chrome mirrors and such are sprayed with a "dullcote", aimed away, some trim sometimes removed or painted over.
Also, different angles & such are edited in during post-production, so sometimes the continuity - small details, the car the actors are in, the background, whatever - suffers.
Some details aren't "seen" by the camera, yet some colors film differently than what the eye sees: tan can come across as pink, dark brown as red, it's a bit weird.
A bit of time, or a re-shoot, chews up a LOT of production money, so the speed of getting it in the can is paramount.
Back then, before CGI, it was all of course basically analog and physical.
