Thank you for sharing your alternative approach. I checked it out and image dimming looks like a fitting addition to dark mode and late-night browsing.
Yes! That is how I originally arrived to it. I have had similar experiences to yours where reducing the impact of the images generally improves my browsing experience. Even in a dark environment, the 50% brightness filter that I use makes the images barely visible. I've found that I enjoy the internet better this way as you have suggested.
