Yes maybe @superceleron can build an Android TV os for vim4 but it will take time.
Oh wait: as i typed this I found that Superceleron have made a test image already.
Yes you can do it yourself. Using the AOSP and then customize it to you taste.
Even after you do all this the widevine level is not change, widevine is the thing that you need to watch drm content like amazon prime, Netflix, Disney+ etc.
So you can only watch them on standard resolution.
