@LimuKhan: I've noticed that this TV is not a UK/EU model - please can you confirm where you are currently based?
In the meantime, please take a look at the guide in the link below from our friends at Samsung US, to see if this helps.

Ambient mode in YouTube would be an app-specific option, and is typically activated by heading to Settings via the Watch page > Additional settings > Ambient mode. Steps can vary depending on the platform (mobile, PC, TV etc) therefore you may wish to reach out to YouTube support directly should you encounter any problems while activating the feature.
