I don’t know what exactly this is measuring, but the amount of daylight in a day does change throughout the year. If this is measuring the amount of daylight gained from dead winter to the shift, then it actually is increasing the amount of daylight.

It’s definitely in addition to dst, look at the southern states… the blue/cyan is 50 minutes (plus 60)

If you are counting the shifting of 60 minutes to the evening, then you o ly add half of the increase in actual daylight per day to the evening because that is split across noon. You don’t add the whole of both to the evening.
It doesn’t make sense to add those two numbers together in any context.
