<< Am I missing a setting? >>

Yes. The six dots indicate No Change in that instruments setting on this bar (the selected bar that's opened).

So, when you say: "I realize the dialog says "Instrument Changes at This Bar", so, technically, the guitar has not "changed" at bar 2. But it is in a different state than the dialog visually presents (at least to me)."
It's not technically correct, it's just correct.

The guitar is unchanged at this bar. It's also not "changed" from whatever setting made prior to this bar and BIAB indicates the change made at Bar 5 with an underline and an underline again when another change is made at at a later Bar.

Adding a status for each instrument and each bar is a much larger and complicated issue than what it appears at first glance. It would require programming changes of thousands of entries. Here's why:

In Bar Settings (F5)dialog window, any change made on every possible entry box results in a red line placed on that bar on the main Chord Sheet. There are thousands of possible entries per Bar Setting Dialog Window being opened because up to 40 choruses each with 255 bars can be activated from the dozens of possible entry selections residing on a single bar.

This applies not only to the 9 instrument volume changes but also to beats, tempo, % change in tempo, key signature change, style change, RealDrums, RealTracks, Notation, drum fills, Patch changes, Harmony changes and every other possible selection that can activated from the Bar Settings Dialog Window.

Accordingly, returning it to normal at bar 9 results in the Chord Sheet displaying a red line on bars 5,6,7,8,and 9.

So, if you mute the guitar at bar 5, what's the benefit of a status other than not changed if there's no change being made to the muted guitar on bar 6?

As things currently are, there's a red line at bar 5 on the main Chord Sheet indicating a Bar Settings change occurred on bar 5, no red line indicating no changes have been made on bars 6,7, and 8 with a red line on bar 9 indicating another bar settings change has been made. The information of Bar Settings Changes is available without the necessity of opening Bar Settings (F5) to see the status of the guitar on Bar 6 that was muted on Bar 5.
