This is something I have studied quite a bit about. Ion trap adjustment that is. As far as I know the ion trap is there to be a "beam bender" and nothing more in most cases. I memory serves me right the electron gun on a CRT that requires an ion trap is positioned at an angle. That directs the harmful ions away from the phosphur screen. The trap actually pulls the needed beam to the viewing area while the bad stuff goes the other way. This is why if your trap is badly misadjusted, or missing you will have no raster.
To answer the question I want to say no, a slightly misadjusted trap will not accelerate the tubes natural degradation. Normally slight misadjustment will give you shadows in the corners or worse a dim raster. The burn is the main thing to avoid....
