you can see just a few big bars with different grey shades. So there is no linear gradient. Also you are able to see some green and some violet bars.

I also tried to instead insert a background image which shows a color gradient but this also looks as described above (we have also tried to maximize the color-depth of the picture but this also did not change the result).
Is it possible that the device is not able to display enough colors for a linear gradient?
Is there another possibility for creating a linear gradient?
