Do Command Line Switches depend on OS platform?

[CL]

I built a Chromium for Android.

 I added some command line switches with official manual

https://www.chromium.org/developers/how-tos/run-chromium-with-flags/#android

Or added it in src directly

//chrome/browser/android/chrome_startup_flags.cc

Then I enabled "Enable command line on non-rooted devices" option in chrome://flags

And I can see the command line switched in chrome://version

I attach the screenshots.

But command line switches never work.

So I doubt that come command line switches don't work in Android.

If yes, how can I distinguish those?
