Netflix has said it has "no plans and sees no need" to add a disclaimer to The Crown to explain it is a work of fiction.
British Culture Secretary Oliver Dowden previously said he fears viewers of the lavish royal drama could be in danger of mistaking fiction for fact without a warning at the beginning of episodes.
It is understood the streaming service has received a private letter from Mr Dowden and has sent a private response.
"We have always presented The Crown as a drama - and we have every confidence our members understand it's a work of fiction that's broadly based on historical events," a Netflix statement said.
"As a result, we have no plans - and see no need - to add a disclaimer."
It is understood that very few complaints have been made to Netflix about the content of series four.
Former royal butler Paul Burrell said the new season is a "fair and accurate dramatisation" of the royal family's treatment of Princess Diana.
