Probably. It's hard to pin down why. Often the display is not
that consistent, or small things (such as moving the instrument)
can change the reading. Sometimes it tricky to hit a particular
brightness and stay within gamut, if the brightness is close to
the limit of the display. Maybe there is a bug in dispcal (I've
looking into this type of thing in the past, but display
inconsistency has defeated any attempt to decide if there is a bug.)

Yes, that's the correct setting for an RGB display.
