The gateway can't affect the noise as that is between you and the exchange.
If you change gateways without a resync you won't see any difference

Short answer, no
Longer answer is that the noise characteristics are from your router to the DSLAM at the exchange. It doesn't have anything to do with the gateway you're connected to.

Remember the reboot will have used the default noise margin which will then vary slightly over time

It just means the noise margin is varying a bit not that it is noisier.
It will probably settle down once the bit swapping has dropped the dodgy tone loading.
Remember the reported noise margin is an aggregate of the noise margin on each tone

This is my noise margin trace without any resync or changing gateways
You can see that, although not as bad as yours, it goes through periods of stability and spiking
