A single instance of something is just that; it doesn't indicate a trend.
Origin
This old proverb is listed in several early glossaries, notably Richard Taverner's transcription of the [Latin] proverbs of Erasmus - Prouerbes or adagies with newe addicions, gathered out of the Chiliades of Erasmus, 1539:
It is not one swalowe that bryngeth in somer. It is not one good qualitie that maketh a man good.
It is interesting that, even in the 16th century, the figurative meaning of the phrase was made explicit.

The comment came in, "...very contrasty overall." I get that a lot. This IS the way it looked to my eyes. At 8500' above sea level, there is little pollution, humidity and haze to cause low contrast images. I know the people who live in the urban areas are NOT accustomed to seeing high contrast light, but that's what we have in my area. (There are no blown highlights or details lost in the shadows.) It's real and it's a joy in my life.
