> Off the top of my head, I can name at least Grafana, Visual Studio Code, and JetBrains IDEs, as the (web)apps that default to dark mode, but have optional light theme. My point (perhaps not worded clearly enough) was that there are very few cases where only dark mode is available. I was trying to say that in most cases where a dark mode has been added, a light mode is also available. I'll give you InfluxDB but, like Grafana, there is a use case of those systems being used on large TV screens so the dark UI has perhaps more of a functional reason behind it than other software.
