for what might be a really stupid

the screens seem much darker than the others?
Presumably some of them have anti-glare screens and some of
them don't.
I remember when those open-weave-fabric-type anti-glare
screens became available in the mid-80s. There were
after-market ones available, we had them installed on our
Ann-Arbor Ambassador terminals.
I don't know whether they were an original or after-market
feature for the Lisas.
They're original. The front panel even has two little metal clips for holding the
anti-glare screen. It just pops in and out, so it's pretty common to see Lisas without
them. A nice feature though, because on the Monitor ///, the anti-glare filter is mounted
inside the monitor, and therefore is not easy to clean. With the Lisa, you can just pop
the front panel off, clean the tube, blow the dust out of the glare filter, and pop it
back on.
