Definitely should be checking certs, though I always worry about the flip side of these device security decisions. if there is no way to update the trusted root certs, your TV becomes terminally ill with software ewaste disease when the manufacturer updates stop coming.

I really don’t like hardware becoming waste because we don’t have a better iot cert pool update story

I trust YouTube to know how to bake their own cert and trustworthy tls libraries into their apps but I’m not sure if that’s common in other apps
