As currently implemented, the invert colors feature doesn’t allow images or videos to be inverted. If the image/video contains dark text or lines on a light background, low vision users can’t change them to light text or lines on a dark background. The issue is system-wide and affects many apps including Safari, iTunes, and App Store.
Workarounds involving screenshots are cumbersome for images and not an option for videos.
1) Add a “classic invert” option and allow keyboard shortcut to toggle between the three (no invert, smart invert, and classic invert).
2) Back out the invert colors change and restore functionality to pre-10.13.4.
