If I were to take a stab at guessing why the left border is extended on some games that do not scroll, I would submit that it's probably to:

• cover sprite on-screen ingress and egress transitions, when the logical object is larger than a single MOB horizontally;
• cover Color Stack advance transitions at the start of a line.
• reduce the effective screen width by exactly one column so that the remaining space could be filled with whatever graphical elements fit in GRAM, while hiding the fact that there is not enough to fill the entire screen.

Or you could take a stab at finding out for sure by using your debugger to turn off border extension for, say, Treasure of Tarmin.

I'm too lazy for that.  The suggestions I offered are based on my own personal experience, which took no effort to evoke at all.

 

I'll leave the actual work to others.
