Just give it another week. I find the green taste usually fades in a week, occasionally can take more.
Take Verdant Putty for example. Hot off the press it's hot and grassy/oniony. A few weeks later it's more balanced.
Other question, is there any hop detritus in your glass?
Batch size?
Double check your bittering hops, I suspect these might be on the high side for a NEIPA/hazy. Move some to a late boil/whirlpool?
Your dry hop amount is also low for the style, it'll probably drop clear, but then call it an IPA!
Hop pellets won't oxidise in a week. They have very little surface area, so you are probably overthinking it.
What I'd be considering most is how you transfer from FV to pressure barrel, as that is by far the biggest risk.
This goes on everywhere.
Brewery, puts up price of cask by 10%, so now Β£1.25 a pint. Pub, puts up price per pint to Β£6+, cites increasing beer costs, wonders why pub is empty.
I've used it extensively, and it was fine. Got good efficiency from Maris Otter in my last brew, nearing 80%.
Previously used a sack of Golden Promise, that too was fine.
This was all from Brewer's Select in Peterborough.
