Thanks for the quick response.

Sure. I honestly wasn't sure which of the 4-years-old requests were still at issue.
From /Applications/Emacs.app/Contents/MacOS/Emacs -Q:

  (let* ((img (create-image (fancy-splash-image-file)))
	 (image-height (and img (cdr (image-size img nil)))))
    (message "%s" image-height))
"16.642857142857142"


Also, I need to correct myself, it looks like I made an error when I said:

  (add-to-list 'initial-frame-alist '(height . 37)) ;; originally 36

was sufficient. It needs to be 38:

  (add-to-list 'initial-frame-alist '(height . 38)) ;; originally 36

Not sure how I jumbled that up.

Sorry, the backdrop of this bug was MacOS ("Emacs master branch built `--with-x --with-ns=no` with full image support on an OSX machine (10.6.8) does not display the Emacs logo ..."), and it wasn't clear to me I should treat reopening an ancient unresolved bug as a new one, but here's the trimmed output from r-e-b:


  In GNU Emacs 27.2 (build 1, x86_64-apple-darwin15.6.0, NS appkit-1404.47 Version 10.11.6 (Build 15G22010))

Anything else that would be helpful?
Is it worth investigating the question of session recovery behavior?
