Significant is very subjective at this point. You are definitely in the harvest window now. You might get a little more weight and/or density from another week, and the high might develop a bit more.
However I don’t think you would really notice unless you had been growing this plant for a while and knew exactly what to expect in the first place

. That’s part of what makes harvest time tough for new growers. Not knowing what to expect from the plant or the smoke/high leads people to consistently harvest early because the “got high last time so it must be done”.
