You can disable play services and uninstall the launcher updates to fix this, then running Netflix will prompt you to enable play services.
Clicking the first "enable" prompt in Netflix will start play services without enabling it and bring you to the app settings page to enable it. Don't enable it. (The force stop button is selectable, which tells you it's now running.)
Hitting back without enabling play services brings you back to Netflix, then you can use most drm streaming services, without play services updating your home screen with ads.
Only catch is play store won't work, but you can enable play services occasionally to download updates or new apps, then just repeat these steps.
