As the industry shifted to OLED (including Google's own pixel series), the cry for dark mode was louder than ever. Google heard the screams and worked towards a true system-wide dark mode. To lay the foundation, they expand all their apps, including the calculator app.
The Calculator app is one of over ten Google apps that have already been given the dark mode. While it's a simple cosmetic change, so many cell phones that use OLED panels make a difference. Since phone manufacturers need to balance the thickness and size of the battery, phones often receive smaller batteries than the users desire. In dark mode, users can maximize this capacity by limiting the power consumption of each pixel in the display.
