That was not what I meant. I was saying Apple has high volume fabrication of 326 ppi LCD screens and also uses 401 ppi LCD screens for plus models. For what they wanted in the XR and 11 they could use either one. But consider that maybe Apple can't ramp up the 401 ppi LCD screen to the volume they need (we just don't know). Apple always goes with the LCD fab that they can scale up in production, hence holding onto the 326 ppi LCD screen for iPhones and 264 ppi LCD screen for iPads. I think Apple might have gone with the 401 ppi LCD screen if they could (or you might give cynical reasons why Apple choose not to). As to LCD vs OLED dpi has always been a source of contention, with OLED having less subpixels in the same screen area, but I guess software can do lots of good things to compensate this in OLED displays, and sure OLED are usually higher in resolution so this compensates for the lack of subpixels. Personally 326 dpi IPS LCD still look fine to me, as I don't put my phone that close to my eyes, but I guess other people do and that's fine and OLED is the way to go for them.
