Should I trim the pale and discolored older leaves? (Hunter’s Vertigo)

I've had this plant for a few months. It wasn't blooming when I got it but it's starting to bloom now.

I'm asking about the yellower leaves that are the oldest and furthest from the center of the plant. They were like this when I got the plant (maybe a bit greener).

They're generally on longer stems compared to the newer leaves (see 2nd picture). I'm not sure if this indicates past etiolation or if this is just what happens to old leaves.

Some of them are have weird "bleached" spots (see 3rd picture).

I don't know if I should trim them to encourage new growth or leave them so the plant can absorb anything it wants out of them.
