Here is one shot at 3200.  Imported to Lightroom and adjusted white balance.

Same as above but exported to Dfine with no manual adjustment.  The above was also with a 50 2.0 v.4.

For these two shots I can see the changes but not sure if they "improve" them.  I rarely use the Nik applications and this is probably why.

Well - this is in the ISO range the M 240 is quite usable. Would be more interesting what it can do with 6400 ISO and banding.

I looked around in my Lightroom and couldn't find any shots at ISO 6400 using a Leica or I would have compared them.  I'm sure I took some but deleted them because of the noise I've encountered.  I'm not much good at PP and generally use a few basic features.  I don't often use the Nik collection but there are some good tools.

Yes, sir!  First and only time there.  Food was fantastic and the margaritas even better.

It can help, but it's not a magic wand!

 

So....

 

Here's a crop of a mundane shot, that's exposed for the highlights - not the subject (yes I know I need shooting, how crap of me. I'd only had the 240 a few days at this point and I was seeing what the sensor could do)

 

The 1/3 SOOC DNG crop

It's ISO200, so let's bump the exposure +2stops and drag the shadow recovery too +75

 

 

Ah hello banding

 

100% crop

 

AFAIK Nothing in LR can make that banding go away... so let's outsource to Dfine 2

 

 

Hidden under the "more" tab there's the debanding tool.

 

 

100% crop

Yeah sure it still looks like shit, but the banding's vastly reduced

 

 

When the .Tiff arrives back to LR I then added +20 L and +6 col NR

 

I don't claim to be an expert

 

But FWIW that's how I've been using Dfine to reduce banding that can happen with 240 DNGs pushed too much in post

 

HTH?

I've found Dfine good also, particularly for noise reduction. Good to know about banding fix.

Advantages..

Seemlessly works in Lightroom and Photoshop and it's free.
