The issue is around how long crews spend at higher cruise altitudes over the period of a month. With more 787's, etc. at FL410/430, exposure at that altitude has to be more than at FL350. Exposure on shorter sectors where the aircraft spends more time at lower levels or on the ground is not as serious..
