SphereReflectionCapture- single vs multiple

Hello, first post, apologies if this has been discussed before, I couldn’t find a relevant topic hence my question.
Say I have a room populated with objects. Would there be any difference in the quality of the reflections if I were to use not one but 4 SphereReflectionCapture objects making sure their radius’s overlap? I currently have one single SphereReflectionCapture which radius covers the entire room.
What is the general rule in this regard?

Thank you very much for any help.

the more captures, the more expensive. that is why on mobile you usually can only get away with 1.

Thanks for the response,
I am creating content for desktop PCs. You say “the more expensive”, I take it you mean “the more taxing” it will be on the GPU to calculate, correct?
But does having multiple SphereReflectionCapture improve the reflections quality compared to having just one SphereReflectionCapture?
