I’ve actually had my first ´frozen in ICE’ behaviour yesterday with 75% charge. 4400km on the car. Stuck in traffic, the meter stayed white until I was way past the traffic and only turned back to blue when I was close to home and I kept switching HV, sport, econ over a period of 25 minutes. Way longer than the normal engine cycle. At very low speed I think the engine was off (it does show EV) but it would turn on when moving, engage the clutch, etc. Maybe this was my first ICE maintenance cycle.
