Just to point out to the devs, I've tested this chrome extension, and getting netflix main profile MPL) in chrome is easily possible with one of this extension's features https:// codeload.github.com/ lkmvip/netflix-4K-DDplus/zip/refs/heads/master
In this extension you just have to choose "play with AVC" under "video configuration" and reload the page, then netflix provides the avc (or main profile/MPL) video stream. I hope that this code (or at least the modified cadmium playercore for netflix) can be used with streamfab's internal browser (which I believe is edge or chromium edge) to allow the user to choose Main vs High Profile (MPL vs HPL) or simply change the default manifest playlist to MPL instead of HPL.

to share with the devs, simply changing the playback default video track codec of the internal browser that streamfab uses from "avchigh" (as it shows when hitting play on a title on netflix within streamfab and pressing the keyboard combination "ctrl-alt-shift-d" and revealing the video/audio information panel) to "avc" greatly improves the video stream bitrate and would thus change "High@L4" shown in mediainfo to "Main@L4" since "avc"=Main=MPL and "avchigh"=High=HPL. I believe that this is a medium priority tweak and it probably wouldn't take very long to either implement an option to choose between Main and High profile (or "avc" and "avchigh") to download, or simply downloading the "avc" Main profile by default. To reiterate, this doesn't require an L1 cdm, it can be done with the chrome L3 cdm that streamfab already uses
