It is just cosmetic, Not really WQHD+ @ 120hz
What your last (3rd) screenshot showing is just cosmetic. Device running 120hz but showing WQHD+ is just a cosmetic.
How to confirm it is really FHD+ or WQHD+ ?
1.Font size is obvious, you won't see any difference by method you shown, in real WQHD+ font size reduces.
2.Take screenshot and open in paint shop or similar that showing size in pixel, it will show 1080x2316 and not 1440x3088 in case you capture in WQHD+
3.Install any app that shows info e.g. ScreenInfo from play store and it will show screen size as per FHD+ and not WQHD+
So with this setup, you are only running FHD+ @120Hz nothing else. If anyone seeing difference from FHD+ @ 120 hz is likely a placebo.
