was mopar blind

if you get the ppg paint chip chart for your particular car, it shows the int colors (codes) used by factory on back side. you will see it changes from model to model somewhat but basically, yes the interior was several different shades. gloss, satin, semi gloss etc.
to me, int does not look right painted one shade especially gloss. but then again a 60's car painted bc/cc shiny does not look "right " either! I say if you want your interior a certain way, then that is what ya should do!
