How number of SSB beams impact on SS-RSRP/Q coverage?

Hi experts!
Do you know how exactly number of configured SSB beams can influence on SSB coverage?

Do we have the same SS-RSRP levels in case of 1 SSB beam and in case of 8 SSB?
As far as I understand total output power is the same.
Difference is in antenna output radiation shape.
So I think yes, there is some difference but it depends on UE position.
