Yes, article title is clickbait. Partial filters don't work, but as they suggest, 100% filter of blue light (resulting in no blue light present), DO work.

You can get this with Apple's strongest filter, the color filter, in Settings > Accessibility > Display & Text Size > Color Filters, rather than night shift. Only red sub-pixels are illuminated with it. It can be added to the triple click power button accessibility shortcut.

That's what I use. I have a shortcut set to enable it when I put my AirPods in at night.
