Native resolution

"No Apple display ever operates at the full advertised native resolution" is NOT true. By default the MacOS uses retina display mode. Retina display typically uses 2 actual pixels to present a picture to the viewer. This typically means a relatively large sized font but something that looks extremely smooth in the curves and so on. Very similar to anti-aliasing.

Now if you're like me you just want more real estate for your apps, you can just opt to bypass all this. There is a *free* app called "EasyRes" which will let you switch the resolution to exactly what is possible by the monitor and if you want to have 3456 x 2234 on your 16" macbook pro, you can. IF the fonts are too small or begin to look jagged then you'll have to sort that out yourself (e.g. resizing, etc.).

However to say that it "no apple display ever operates ..." ... nah. Not true. It is actually possible, even if it's not common.

For the record, I normally use 2880 x 1800 because after that I find it's a little too narrow sometimes and if I have to increase the font size then it sort of negates the whole purpose because I did it to fit more lines in the screen at once.
