For me, only the preview in LyX: LaTeX handles the EPS without troubles.

Isn't there a difference in the number of supported formats? Both are quite
copious (https://imagemagick.org/script/formats.php#supported vs.
http://www.graphicsmagick.org/formats.html), I'm not sure there's any
noticeable difference for a LyX user.

Digging deeper into Photoshop's behaviour, it seems that the TIFF portion
is a low-quality preview of the actual content (by default, using only one
bit per pixel). Among the two images output by ImageMagick (with a simple
magick $$i.eps $$o.png), the preview is the second file ($$o-1.png), while
the expected one is the first ($$o-0.png).

As I understand, the standard behaviour with pdflatex is to go through
epstopdf, which internally uses GhostScript. It doesn't care about the
preview and only outputs the image that corresponds to ImageMagick's
$$o-0.png.

(However, I'm really unfamiliar with TeX and derivatives' code source, so I
could not really triple check this.)
