What's happening to the colours (JPEG export)?

What color profile did you save the image in?I am puzzled why the colours of the image edited in DxO PhotoLab 2 and exported to JPEG are different on the same display device:

Also be ware editors like DxO, Photoshop, Lightroom are color managed in a closed environment. So if you saved an image in say Adobe RGB in DxO tried to view it in say Windows Photo it's not going to display correctly because Windows itself isn't color managed (keeping things simple).

My monitor's profile.
It seems that microcontrast and sharpening during export can affect the resulting colours quite a lot. When I turn both off, I get warmer tones.

You should never embed you images with your monitor profile because those are too volatile. You need to save them in either sRGB, Adobe RGB, or ProPhoto. Those are the recognized standard color profiles an image should be saved in.
At any rate, as I said, the Windows Photo app is not color managed so you won't get matching results with it.

Sorry, I misunderstood the PL 2 settings. I use my monitor's profile for display, and use the "Original" ICC profile when exporting. My camera is set to use sRGB, so I understand this is the "original" ICC profile in the RAW image. Thus, I believe I export the image to JPEG using the sRGB profile. My monitor (according to reviews) has 100% sRGB coverage.

Sharpening during export seems to make the image look cooler:

OK, I don't use DxO so I can't speak to setting but I'm sure it has a color management setting you're not using.
That said, when editing an image in a photo editor, you need to first set up it's color management. Then when you edit your photos, that profile will be saved to your image. This can be sRGB, Adobe RGB, or ProPhoto. Never the monitor profile. I'm keeping things simple as there seems to be a lack of understanding here. This not meant to be a knock but to help.
With that you need to revisit DxO and check your color settings. I'll see if I can find a YouTube clip on setting up correctly. Which DxO product, and what version?

I think this is a better description of how DxO uses ICC profiles then I wrote: http://forum.dxo.com/index.php?topic=6580.msg38870#msg38870
So the only stage at which I could *change* the ICC profile in my image is during exporting. Prior to that, I can choose the ICC profile used to display the image on screen.

On the first post, it looked like you were using Windows 10 Photos app to view the image?
Windows Photos app is not colour managed, so colours will generally not be correct, whatever colour space you use.
DxO, Photoshop, Lightroom and virtually all non-Microsoft photo editing or display programs are capable of colour management (not always the default option). Similarly, Firefox, Vivaldi, Chrome and Safari browsers are colour-managed.
Most Microsoft programs are not properly colour-managed, and usually ignore the monitor profile. This includes Windows Photos App, Edge and Internet Explorer. However, the old Windows 7 "Windows Photo Viewer" is colour managed and is shipped with Windows 10, but is disabled by default for jpegs. Google for how to enable Windows Photo Viewer on Windows 10 (usually involves a registry patch, but plenty of sources of exactly what to do).
Why Microsoft are still in the Stone Age for colour management is anyone's guess.

Good point. But Chrome also displayed a difference after I uploaded the same photo to Google Photos.

After switching to another browser which does colour management (Faststone), I can confirm that the main reasons is sharpening during export. My images had lots of leaves in them. Leaves have edges, and their edges get brighter during sharpening. Result: a brighter image. I turned off the sharpening for those photos, and voila, my problems are mostly gone.

I don't use Google Photos; does it strip out embedded profiles when you upload? Some cloud services do.
How does Chrome display the image before you upload it? If you just open the image as a jpeg from local storage.

I haven't checked, but (if you see my other post) I fixed the problem by changing sharpening settings.
Both images look identical when it comes to colour when viewed in colour-managed programs on my end (Firefox, FastPictureViewer and Affinity Photo). The first one is oversharpened, though -- you probably used DxO's bicubic sharper option when exporting and resizing (I suggest resizing in a different program than DxO).
FastStone tries to do colour management, but it's incorrect. Don't use it to troubleshoot colour-management problems!
As the two other posters in this thread have already suggested your problems stem from comparing the previews of your photo between non-colour-managed programs (Photos, FastStone) and a colour-managed one (DxO). My suggestion -- instead of using Photos or FastStone have a look at XnView MP (or IrfanView) and set them up so that they recognize your monitor profile.

I like to use one program for everything, but DxO has problems with over sharpening during export and no option to control it.

Thanks I did that. XnView MP can act as a host application for some of the Nik Collection plugins, too (I got Sharpener Pro to work).
Yes, some of my Ps plug-ins work in XnView MP, but some of them crash the program. I haven't really investigated the issue because I use PsE or AP as the host.
You could convert your raw files from DxO in the original size and then use XnView MP to resize them (using the Lanczos resampling method) and then sharpening them -- the batch convert tool allows you to do both things at the same time, but the Nik Sharpener Pro will give you even better quality than the simple USM routine in XnView MP.
XnView MP -- the Batch Convert tool

I'm leaning towards that, although it will cost me more time than just doing everything in DxO... I often upload my photos in two sizes: for Google Photos (with 4096 maximum size to avoid paying for storage) and for Facebook (with 2048 maximum size; I upload for FB to get charity likes from friends & family 
). And some of the bird photos get also resized to 1024 max. size for upload to BirdForum. It was very easy to export a photo to 2 or 3 formats straight from DxO. Manual resizing and sharpening in other application will cost more time. But DxO sometimes oversharpens horribly during export...
