TTN indeed uses 869.525 with SF9 and 27 dBm high transmission power for RX2, and in the early days preferred RX2. However, [nowadays it prefers RX1](https://www.thethingsnetwork.org/forum/t/why-is-rx-slot-1-not-used/2656/5):

RX1 uses the same settings as your last uplink, and regular 14 dBm transmission power. So, despite the title of your post, I assume you’re seeing RX1 in the last two examples above (and indeed RX2 in the first example).
