Astrophysicists unveil biggest-ever 3D map of Universe:

The map is very isotropic and homogeneous, the large scale galactic filaments are not as apparent on this scale. Discussion?

Isotropic:
.(of an object or substance) having a physical property which has the same value when measured in different directions.
.(of a property or phenomenon) not varying in magnitude according to the direction of measurement.

Homogeneous:
.of uniform structure or composition throughout.

Thanks for the link. Nice to see additional validation for the cosmological principle. 

Will study in more detail

Affirmative. I have located the official "Extended Baryon Oscillation Spectroscopic Survey (eBOSS)" website, listed in reference.

The eBOSS team is using a universal time coordinate scale as the domain axis on their map, however, I am also interested in examining the CMBR photon surface of last scattering radial metric distance used on this map, the metric correspondence between space and time, called space-time.

If anyone is able to cite a reference to that eBOSS CMBR radial metric data, please post a reference link.

This is the YouTube "visualization of the data" video linked from their website:
