Just notice iPhone 6 Plus is not FHD (1080×1920) but more than that.
Apple still as usual using weird resolution.
iPhone 6 Plus is
1242x2208 resolution.

You're misinformed regarding resolutions for the new iPhones:
6 Plus: 1080p, 401 ppi
6: 750p, 326 ppi
For 6, all user interface elements and content are rendered pixel-perfect in @2x resolution. If you take a screenshot, the image will measure 750x1334.
Here's where it gets interesting. For the 6 Plus, everything is rendered at @3x resolution. If you take a screenshot, the image will measure 1242x2208. However, the actual screen hardware is only 1080x1920 so iOS downscales the whole user interface to fit the screen. My guess is that Apple wanted a 2208 × 1242 screen but couldn't get enough of them at a quality they were satisfied with. I expect iPhone 7 Plus to have a true 1242x2208 screen.
Here's what John Gruber of Daring Fireball said (scroll down to Display Quality):

The Plus, though, works differently. Physically, it is a 1920 × 1080 display with 401 pixels-per-inch. Virtually, however, it appears to apps as a 2208 × 1242 display with 463 pixels-per-inch. Those latter numbers should sound familiar to regular readers. The iPhone 6 Plus automatically scales the 2208 × 1242 interface to fit the 1920 × 1080 display. This on-the-fly downsampling sounds crazy — it sounds like something that might be slow, and that might lead to fuzziness on screen with small text or fine lines. In practice, it just works. Text and fine lines appear sharper on the 6 Plus than on the regular 6 (or any other iPhone with a 326 PPI display, like the 5’s). 401 pixels per inch is high enough that things still look great even if they’re not pixel-perfect. I was deeply skeptical of this on-the-fly downsampling when I heard about it, but having used it for a week, I’m sold.
(When you take a screenshot on the iPhone 6 Plus, you get a 2208 × 1242 image — you get a screenshot of what the app thinks it is displaying, not a screenshot of the actual pixels on screen. If you really do care about pixel-level precision, I’m not sure how you can tell what is being rendered on screen other than to examine the actual iPhone display using an optical loupe.)
