We focus when we think of the solstice on the length of the day, but I wonder how much that’s it and how much it’s the quality of the light, the angle of the sun, that makes this time of year miserable. Today it looks like the sun will not get more than 15° above the horizon

Hypothetically if the sun reached the heights it does in Summer during the 7h42 of daylight we get today, would it be more pleasant? (Assume for the purposes of this exercise that I’ve arranged the physics to work to permit this somehow. Either the sun operates like a lightbulb or speeds up or something.)
