Hate to be beat. Lots of messing around resulting in a very simple
look-up-table.  A tiny png (8 pix) g2.png attached.

Again uses g'mic plugin from www.gmic.eu This time in the 'Film Emulation'
section as 'User Defined'.

The gmic dialogue is in the screenshot.

As before the result is shades of gray and RGB, use Image -> Mode -> Grayscale
to finish.
