I'm still struggling to understand that whole workflow and it looks like this is no easy way of getting to the bottom of this.

But adding kwarg extend="max" to the calls to pcolormesh/imshow fixes this.

The docstring gives a hint:

extend : {'neither', 'both', 'min', 'max'}, optional How to draw arrows extending the colorbar beyond its limits. If not provided, ``extend`` is inferred from ``vmin``, ``vmax`` and the data limits.

So in first case everything works nice since extend is derived from vmin/vmax and data limits. In the second case, extend is obviously not set to the expected value (as in cbar_kwargs) as we've tampered with the maximum data values.

Not sure if aligning extend and cbar_kwargs-extend is already the solution.
