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.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1368027148
