Currently, the "Player Entity" element doesn't display visual features from the Ears client mod.

Not sure if this is relevant feature request but I'd be pretty happy to see support for it.

Here is a side-by-side comparison of how my character looks like in the Player Entity element vs in-game.

Thanks for considering!

Edit: I also feel like it would be nice if the Player Entity could display the current in-game player character appearance like armours and held items. Just like in the survival inventory screen.

Will probably not add support for that mod, sorry.
It's also not really possible to reflect the world player, because you're not always in a world when Player Entity elements are shown.
