Youtube visualization of the additional new data the study contributed (eBOSS):

The linked phys.org article btw didn't say very much. Would be nice with a summary of the actual scientific impact.

As far as I could tell, for models of cosmological growth, it tightened the limits on dark energy to match the standard GR type even more but no new odd things appeared.

I read these findings rather differently. The "expanding balloon" spacetime predicted from GR may absolutely be in question. It appears every type of measurement confirms a discrepancy in the Hubble Constant with respect to distance. Though none of the results from different spectra agree with each other. As new observations from next gen wide array sources such as the Vera Rubin Observatory and James Webb Space Telescope come online, the risk is that the overall picture becomes less clear with higher accuracy ;)
