I think Apple shipped some computers before with less that 24 bit colors they claimed. I don't have a link to prove this, but I remember reading about this some years ago

It's become common for 6bit panels to advertise "millions" of colors even though it's not possible. They count things like dithering. So if you have to colors next to each other, squint so it's blurry, you'll see them as a third color and that's what they're counting.

Actually that's not how they do dithering in LCD panels. It's time-based dithering, not proximity-based. They just take the same pixel (RGB subpixels) and quickly switch between the 2 supported colors at the appropriate amounts to simulate the desired intervening color. It works quite well but you can tell which panels are doing this using certain techniques.
