The typographer's rule is, "If it _looks_ right, it _is_ right," and the decal as shipped looks fine, typographically. We make these slight "adjustments" all the time, it's a big part of the job (especially for logos) - and reveals that a professional was involved. Usually people don't even notice them, because that's the other rule of typography.

There are other examples in our field of lettering that changes according to context: the font used by DEC on the PDP-11 handbook covers and a number of peripheral device panels.  The letters "t" come in "big loop" and "small loop" forms.  The big loop is used when there isn't another letter after; the small loop is used to avoid looking silly when another letter follows. Look at "digital equipment corporation" on the inside cover page of the PDP-11 processor and peripheral handbooks, it shows it clearly.

I digitized that font and gave the same treatment to f, j and r, though I haven't seen those differentiated in the examples I looked at.
