Generally yes, a 3mm added width should be no issue. BUT if your rims are already at the caliper's limit then even 3mm will be a problem. This we can't say as we don't know enough yet or we are not there.
I will add that this is an issue for those who have calipers that were designed around the 23mm tire/20-22mm rim (outer) widths that were so common just 5+ years ago. People want to get fashionable by replacing their wheels with the current wider ones and are finding their calipers no longer have enough travel to allow the QR to fully function. Just one more "cost" of having been in fashion those 5+ years ago
