Siri problems when used with homepod to remote control apple tv

Hi,

I am interested why I can't use the same Siri commands that I use when opening the apple tv remote in the iPhone control center and press the side button to activate Siri.

Here is a simple example:

Command for iPhone remote Siri: Hey Siri, show me popular Christmas movies.

It brings up a list of popular Christmas movies available on my Apple tv on my TV screen.

Command to homepod: Hey Siri, show me popular Christmas movies on Apple Tv.

Siri responds by saying "I couldn't find that on Apple music.

But when I say, "Hey Siri, play FRIENDS on Apple Tv, it brings up a list with different shows with the word FRIENDS in them.

My question is this: Is there a way to make the homepod Siri respond the same way as the iPhone remote Siri?
