I think if it can be done right and in the right show, it could be ok. I was fine with all the real life products in LB, and thought it was fine and nothing that pulled me out of the moment (which I feel like if they drank OrangeBull or something silly like that it would have)
That being said, shows like Blonde it can work fine it, but there are plenty of shows, such as period pieces that I don't think it would work in, and hope we never need to see Phantom 2 with a giant chandalier from chandaliers.com or Cats 2 wearing pedmeds.com flea collars.
