@jeffersonmueller, go to MoreWine! and download their red and white wine making manuals. Do NOT try to read them cover to cover -- it's too much to absorb at once. Skim the white manual to get an overview, and then do the same for the red -- the differences for reds are mostly up front. Later go back and read in detail.

It's not an improvement, just a placebo. The wine will oxidize with that much headspace. I allow 1" to 3" of headspace in a carboy, with my typical being 1-1/4" to 1-3/4". In the following picture all headspaces are 1-1/4" to 1-1/2":

Many moons ago a customer had a wine going great (I co-owned a LHBS), Niagara IIRC. She bought the juice in Oct, and everything was going great. I didn't see her over Christmas that year, and she came back in the shop in February wine a sample. Her wine was oxidized.
She and her husband had been drinking from the carboy -- they apparently missed the "bottling" part. I recommended she hit it with K-meta, bottle, and use it up.
Oxidation is like a car accident -- it's best handled by avoiding it.
This thread is a good illustration of 2 points: 1) when giving advice, ensure the recipient understands. and 2) Keep asking questions!!!
"Ignorance" is the most appropriate word.
ignorance
ĭg′nər-əns
noun
The condition of being uneducated, unaware, or uninformed.
When I was a kid, "you're ignorant!" was a put down uttered by ignorant children.
But the reality is everyone is ignorant about many things. This condition is easily changed by learning.
