Coolant temp slower to rise than oil temp on Carly

Noticed that my coolant temp is very slow to rise from startup...

From cold start to around 80C motor temp, coolant temp shows 40C. It really takes a while in a slow traffic to get to 70C, and hardly goes over 80C even under moderate to hard load. Is it normal motorwise? I feel like the rise of temp should be the opposite... Motor temp is consistent.

There's no code related to water pump either. (only a record of 00A6D1, hasn't yet appeared after I cleared the code)

I also thought of possible explanations:

1. Open thermostat
2. Cool ambient temp (currently around 0-15C. I logged it at 15C.)
3. High water: antifreeze ratio (e.g. 7:3)
