The use of a spherical wave instead of a plane wave physically changes the magnification of the object you are recording. You can also change the magnification by using the numerical reconstruction wave. In all cases, this results to the modification of the reconstruction distance that will give you the focal plane. You can find more detail in the book of J. W. Goodman, Introduction to Fourier Optics, 2nd ed.
(McGraw-Hill Editions, 1996); or in the section 3.D of this paper: Picart, P., & Tankam, P. (2013). Analysis and adaptation of convolution algorithms to reconstruct extended objects in digital holography. Applied optics, 52(1), A240-A253.
I agree with the answer given by Patrice;
In addition, basically, the hologram looks like a hologram recorded with a plane wave

I would like to recommend for calculation of magnification and aberrations of a hologram recorded by spherical wave the paper:
R. W. Meier, “Magnification and third-order aberrations in holography,” J. Opt. Soc. Am. 55, 987–992 (1965).
The simplified version of this can be found in the book:
Robert Jacob Collier, Christoph B. Burckhardt, Lawrence H. Lin. Optical holography, Academic Press, 1971.
Sure, the Meir formulas can be used also to the hologram recorded by plane wave considered as a particular case.
