Mull and Android WebView

for anyone using Mull on Android, since i'm using it that the webview i see in apps like Feeder seems to be using Mull, although when checking the implementation in Dev Options, it does look (from logo and name lol) like normal Chromium webview

what's really going on here, and how could i have properly checked it myself?

EDIT: vain attempts at posting inline image instead of link to hoster

EDIT2: thanks to noodlejetski@lemm.ee with the image thing (dumb me thought [] was that rectangle character you get in some fields where that character is not recognized ಠᴗಠ )
