Several ideas how a recording should sound to be "good".
Blumlein, bin-aural, RCA living stereo had similar concepts, but with some differences. Check some audio engineering books.
Those early concepts, superficially simple gave way to close-miking and heavy post processing.
"Simple" minimalistic recordings, that includes room acoustics, can sound really nice. Example: Andrews Sisters' Rum and Coca-Cola, etc.
Expectations and taste.

Except for all being some form of stereo, Blumlein, binaural and Living Stereo have nothing in common.
Blumlein nowadays refers to a coincident pair of figure eight mics at 90 degrees, and although first described by Alan Blumlein, the technique was not called that in his lifetime.
Binaural was the term first used by Alan Blumlein to describe two channel recording, but was quickly replaced by the term stereophonic. The term binaural is now used only to describe the dummy head technique where mics are placed inside an artificial human head (or worn on/in the ears of a person). It's part of a broader class of stereo techniques known as 'near coincident', where there is a small space between the mics; ~7"-12" (including ORTF, NOS, Jecklin disc, etc.).
Living Stereo was not a mic technique at all, but an umbrella marketing term used by RCA for their early stereo releases, both Classical and Pop; though most of their Classical sessions were done with what is now often referred to as "M3" (three
widely spaced mics; usually omnis), none but the very earliest releases were pure 3-mic affairs, but used several spot mics as well. What
were pure 3-mic "M3" recordings were Mercury Living Presence, most of the Everests, and the first several years of Telarc.
