Would grout spray help? I’ve been in my home for 3 mos (new build) and it’s so annoying

This is just dust from the marble.

Are you guys positive it’s shedding from the marble? Because I have white bathroom dust and it is…toilet paper dust. I know this because I kept a lidded trash can underneath the roll and had to dust it constantly. Finally I realized the dust was being shed by the roll. Costco brand, if anyone wonders.
