The displayed range on startup is really just based on your current average efficiency + exterior temperature. It dropping precipitously under those circumstances isn’t concerning.
Overall, I’d focus on how much % SOC you use and get a feel for your commute rather than worrying about displayed range. That’s just the car trying to estimate based on external factors and isn’t worth worrying too much about until you’ve got quite a few miles on the car and it’s got a better estimate of your averages.
It seems like the display hardware is there, I think the biggest blockers to truly indistinguishable MR are FoV (which theirs is good but still not truly indistinguishable) and the cameras feeding data the outside world in which will always adjust differently to contrasting light and changes in focus than our eyes will.
