Turning on/off the comics mode does not change anything in my case.
Well, I'll try to explain. My English is quite poor, but I'll try.
I opened a djvu file, set BBox leaving small white margins on the left and right of the text. When I turn on "Fit to content" or "Fit to content height" mode, the left margin (white field) is that, which I set by BBox, but the settings of the right one is ignored - the right margin is bigger than I set, it continues from text to the page edge. The pages are centered by the grey fields on the left and right, but the white margins are wrong.
It looks ugly enough, and I expected the other result. If I set the right margin, I would like to use it, won't I? But the setting of right margin does matter only in "Fit to content width" mode, not in other "content" modes.
Now I'll attach a couple of screenshots to make it clear. The same page with the same settings of BBox, but in the different modes - "Fit to content" and "Fit to content width". The "Fit to content height" treats the same way as "Fit to content".
