Back on August 31st I posted that "getting the reverberant field right" matters if rich and natural-sounding timbre is a high priority.
I think there was a fair amount of skepticism, with @prof expressing it well back on September 8th: "I’ve never heard more room sound contribute to more accurate timbre."
I’d like to offer a youtube video of a presentation by acoustician David Griesinger. David investigates concert hall acoustics, and he has determined which reflection are beneficial and which are detrimental based on timing. He is going to demonstrate this by playing four clips that include and/or exclude early and late reflections.
First, he will play the direct sound only. This clip is time-gated to exclude all reflections, so it sounds thin because the longer wavelengths are also excluded. The singer’s voice sounds "proximate" (up close) because of the lack of reflections.
Next, he will play the direct sound plus the first reflections. The timbre will be a bit warmer because longer wavelengths are included, but the clarity will be significantly degraded.
The third clip is by far the most interesting: Direct sound MINUS the early reflections but INCLUDING the later ones. Now we have clarity along with our elusive friend, Rich Timbre!
The final clip includes them all: Direct sound + first reflections + later reflections. Timbre and clarity are both degraded relative to the third clip, but timbre is still better than the first and second clips.
Here’s the video, start at 13:19 and go to about 15:02, headphones or earbuds recommended:

Just for fun, go back to 14:20 and listen to that third clip again. How about THAT timbre?? Imo THAT is the target!
I believe the psychoacoustic principles demonstrated in David Griesinger's clips have validity that extends beyond the concert hall and into our home listening rooms.
As these clips show, EARLY reflections are detrimental, but LATER reflections can be quite beneficial, enriching timbre with no degradation of clarity. So "more room sound" CAN result in "more accurate timbre" IF it is done right.
