That 4K render of an iPhone screen is so uselessly accurate it's great.

Neat, but I kinda wish manufacturers would quit making cursed displays like this.

Either follow the existing convention, or try your best to hide the subpixels entirely.

This seems to treat one white dot as a green subpixel which bleeds 25% into the diagonally 4 adjacent red/blue subpixel. I've always seen pentile subpixels represented as groups of 2 element subpixels https://geometrian.com/programming/reference/subpixelzoo/squ... or diamond shaped gorups of 4 subpixels, 2 of which are green https://global.samsungdisplay.com/wp-content/uploads/2021/11.... In either case, the green subpixels tend to be smaller in response to their increased prevalence.

The colour tinting of the mac icon and folder examples implies that their code isn't accounting for gamma curves properly, I might see if I can contribute a fix.

I love this. I tried doing sub-pixel simulation for a tool I created (screenstab.com if anyone’s interested – yeah I know, shameless plug, etc.). I ended up abandoning the sub-pixel aspect in my shader because of the distracting patterns caused by the Moire effect.
