Wait, wait. There is no setting named 'manual white balance.' You have to select a setting when you manual white balance. Settings include a color temperature and also 'native." If you choose 'native' you get the flatness you have observed for sure. When you choose, say, 6500K you will get a different look that is more saturated.
So, are you talking about 'native' WB versus Auto WB or what? There is no manual white balance' setting - just Auto and then either a specific temperature or 'native.' Even the moderator seems confused.

The Flat Color and Native WB look fine to me.
These 2 settings don't adjust any of the colours in the image so that colour correction/grading in post with a suitable editor can be done without the saturaion added in by the camera.
Auto WB will adjust th RGB colour levels depending of their amounts in the image, which sometimes ends up in poor results (e.g. when their is a dominange of green in a forest). Gopro color profile alters the saturation of all the colours to make them pop. Both actions can, under certain circumstances, result in colour levels being pushed up to their maximum and being blown out loosing details.
A Flat unchanged image is preferred when the images are going to be post processed and colour graded in software such ad DaVinchi Resolve which offer greater control over the alteration of colour values so that the editor can match the colour between different cameras easier and also give a specific look to a project. These flat images are not meant to be used directly but to undergo post productions editing.
What software are you using to colour correct/grade and what are the results?

I used the term "manual white balance" to illustrate that no K value is immune to the problem (ignoring Native). And the issue isn't with color temperature, it's that the temperatire setting alters the saturation.
For example, when using GoPro Color + Auto WB, the image will look "correct."
When using Flat + Auto WB, the image will look less saturated, but the color temperature is still relatively accurate.
In either of these cases, the user can manually select a white balance value and make the image look very close to Auto WB.
- GoPro Color + Auto WB on a sunny day looks very similar to GoPro Color + 6500K.
- Flat + Auto WB looks normal-ish on a sunny day, but Flat + 6500K (or any other selection) is dramatically different.
When using GP Color, one can either use Auto, or "stick" the white balance with a manual selection.
When using Flat color, while mildly desaturated, the Auto WB color temp is still relatively accurate.
As soon as you switch from Auto WB and choose a manual WB option when in Flat color, the ***saturation*** changes. This is the issue.
See earlier screenshots.

Anyway, to prevent going off-the-tracks, please just try the original steps. When in Flat color, choose any K value. If your image doesn't suddently dump almost all of its saturation, your camera doesn't repro the issue.

Adding there is not only desaturation, I also observed color shifts, for example from red to orange. Simply adding saturation in post doesn‘t bring the right color back.
I already posted this here including a video:
This can‘t be a big issue since the colors are still right during the selection of a whitebalance preset.
Only when the value is applied colors go wrong.
