Likely yes.

In fact, ob-latex is making use of `org-preview-latex-process-alist'
only in a single cond branch in `org-babel-execute:latex' - when we have
:file foo.png

However, that branch assumes that `org-preview-latex-default-process' is
'dvipng (the default value). If one changes it to, say dvisvgm, the
generated image will not be a .png image:

(setq org-preview-latex-default-process 'dvisvgm)

#+begin_src latex :results file link :file test.png
x^2
#+end_src

#+RESULTS:
[[attachment:test.png]]

^ This is actually an svg image, renamed to "test.png".

So, it makes sense for `org-babel-execute:latex' to override
`org-preview-latex-default-process' temporarily, to something actually
generating .png file.
