Sure,

I knew I wanted something like the inlineimages STARTUP keywords. So,
I've searched in the source all references to inlineimages.

M-x moccur-grep RET inlineimages RET

I've found:
a custom variable: `org-startup-with-line-images'
an entry in `org-startup-options'

Then I've searched for `org-startup-with-inline-images' and found:
> (when org-startup-with-inline-images
>       (org-display-inline-images))

Then, I've searched the name of the function which toggled the latex
preview. C-h a latex RET then C-s preview in the *Apropos* buffer.

At this point I had everything and I just needed to copy what was done
for inlineimages and adapt it for latexpreview.
