B&W JPG recipe in-camera?

I’ve been shooting JPG+DNG with B&W previews in camera. 
 

When I import the DNG into LR and convert to B&W, it becomes apparent that Leica’s JPG recipe involves a slight color tone by comparison. I quite like the look of the JPEGs.  Has anyone come up with a LR preset to mimic the in-camera BW Leica is using? The JPEGs have just a touch of vaguely greenish warmth, almost like a platinum print. LR’s BW is truly monochrome, but by comparison to the Leica JPGs, it feels cool and bluish.  Obviously I could play with the LR sliders but I’d love something more automated.

You could try using Capture One's Match Look Tool on a JPEG + DNG pair of the same image. Set the JPEG as the reference file and apply the look to the DNG. Then you could save those settings as a preset. 

If you don't own Capture One, you can download a demo. See what image adjustments Capture One is applying from the Match Look Tool, then use similar settings in Lightroom.

What are you viewing them on?

Thanks. I’ll give C1 a try. 
 

I’m viewing these on an iPad Pro 13.

Generally I find the Leica b&w JPEGs have some minor adjustments to the color channels that can be mimicked in the C1/LR b&w panel (reduced cool sliders and increased warm soldiers). They also seem to have a tone curve applied to the entire image, but I could never replicate it exactly. It will be interesting to see if C1’s match look tool works for this — please report back how it goes.
