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.

As the number of beams increases, the beam width reduces. So the output power is concentrated in narrower region and as a result the coverage increases.
