What I mentioned (chalked white vs. still-good black plastic molded door panels) was what members of our Mopar club determined from their quest for better interior pieces than what they had. And that was in the later '80s and earlier '90s. Everybody wanted to see them in repro, but it didn't happen until later.
When I started to frequent local salvage yards in search of future-need items, it became obvious that the interiors of Chrysler products were in better conditrion than same-model-year GM cars. Chrysler obviously chose better materials that held up better.
Consider, too, that Chrysler typically did not service soft trim items after the first model year of production, whereas GM and Ford did. So if the car got out of the initial warranty period, there typically was no need of those parts by customers, so no need to stockpile such parts as GM did. Resultingly, they had to be better to start with so they ended up lasting much longer into the vehicle's total life. Seat covers got a burn hole? To the trim shop. Other things, the salvage yard.
As for white seats, I normally wear blue denim jeans. Even get a bit sweaty in them, too. When damp, that blue will transfer to other things, like seats (cloth, vinyl, or otherwise). Once there, it's hard to get off/out. Which makes darker grays/black shades a much better option for me. One year at the Fort Worth new car show, there was a new Lincoln SUV there, with the white interior. After two days of being on display, with people getting in and out of it, the white leather driver's seat already had a blue tint to it, especially on the outer edge of the seat cushion. I laughed when I saw that as I knew where it had come from. Certainly not from slacks.
Y'alls sensitivity to such things might be different than mine, which I respect. Certainly, a white interior tends to look more open and expansive than other colors. Many look really nice, too. Ever wonder why the white seats were usually paired with black carpets?
Just some thoughts and observations,

I had a 72 Challenger with a white interior and all the hard plastic was chalk, that was in 92.
