Are F1 races on Apple without F1 TV app

What link are you trying to find?

Samsung smart TVs have their own on-device App Store to find apps that are available on it but haven’t been installed yet. Searching “Apple” should help you find it.

Subscribing to the Apple TV streaming service is described here: Subscribe to Apple TV - Apple Support, but can also be initiated through the Apple TV app on your TV (sometimes with help from a computer or mobile).

Get the Apple TV app on your smart TV or streaming device - Apple Support

… but cannot find any mention of the F 1 races in the programs

I expect F1 tiles will be added to the app once content is available for the app. They haven’t publicly stated their start date yet. I’m sure Apple wants impressive viewing numbers to validate their involvement; there will be additional promotion closer to premiere.

Not sure (but hope so) if the pre-season test drives in Bahrain (11–13, 18–20 Feb) will be included already,

else the competition starts for real on 6–8 March in Australia.

In the US, yes, this will be in the Apple TV app, for subscribers to the Apple TV streaming service.
