The alpha channel of the cell color is based on the cell value itself and the possible min/max value of that cell. Note that the display value of a cell can be different from the actual value. Can it be that these 2 rows are different in that aspect? The hue of the color is based on the current alarm state of the cell. It is currently not possible to disabled this feature. If you would like to be able to configure this, you can create a feature suggestion.
