I don't even notice it, the ad starts out small at the top and your cursor starts out on the Apps row, you have to very intentionally trigger the ad.
90% of the time the ads are for movies or TV shows on the streaming services you have installed (and presumably an account for) anyways, so there's been non zero times where I did go abd hover the ad to watch it cuz I was like "oh hey I actually wanna watch that, is it coming out soon? No shit!"
The other 10% if the time it's mcdonalds or Harvey's or whatever, I barely notice it as I spend pretty much all of my time with the Google tv "inside" an app.
Very little time gets spent on the home screen, it's a glorified Start menu to pick an app and open it up, so I don't, to be blunt, give much of a shit that for half a second I can see a big Mac at the top of my TV screen before I click the 1 button to open Netflix.
Also more often than not I use my phone app to push to the TV, so my process is:
- TV is turned off atm, I open on my phone (Netflix, Disney plus, crunchyroll, Amazon prime, YouTube, etc)
- I click the cast button on my phone
- TV auto detects activity, starts turning on, meanwhile my chromecast is already loading up the app and booting into it
- By the time my TV screen flips on, the app is opened as well and my content starts to play, so u never even saw the home screen in the first place
End result: I rarely even see the app realistically anywho.
