I wouldn’t say it’s an ash blonde at all.
Your roots look like an ashy light brown and the blonde looks like a dark neutral blonde - I wouldn’t say it’s golden nor ash.
The “goal” photo looks more platinum and ashy (it’s highlights so there’s a variation of colour). I think the largest difference is that your hair hasn’t been lightened enough - I reckon if you had the same tone but a lighter blonde you’d be happier.
I think ask the salon for a bleach cleanse & toner.
