It's interesting how the TOS crew aged between TMP and TWOK. I know canon-wise the movies take place about fifteen years apart, but in the real world only three years passed, and in TMP they don't look all that different from TOS, except for the dated uniforms and hairstyles. Since aging is one of the themes of TWOK it's kind of fitting....
I think that's why the dim lights in TWOK were a way more unforgiving than in TMP.
