Are there ultra realistic texture packs / shaders for Minecraft Bedrock Edition?

I realize that there's no such thing for Bedrock:

But aren't there any realistic graphics for Bedrock, so that the gameplay e.g. Is it even better on a smartphone? Can someone send me a link?

As far as I know there's the beta of the Nvidea shader. LG

Well, unfortunately this shader is only available on the PC…
