It's night time. So my pictures are not great. But you will get the idea.
The inside one is showing a high ceiling. No attic, no crawl space.

If your house is not that old your cathedral ceiling cavity between the roof and interior sheet-rock is probably well insulated with as much insulation as needed or can be stuffed in the cavity. You can kind of judge by the snow on the roof.

I have a room like that and all is well.

If frost and snow melt quickly on that section of the roof there is not enough insulation.

If there's snow sitting on your roof, it must be well insulated. Otherwise all the heat in your home rising into the peak would be melting the snow on the roof.

Not true.
My neighbor has a lot of snow on his roof.
He also has a 20 feet wide row of icicles that are on average 4-5 feet long.

So I guess icicle length is a better determining factor than snow accumulation.

No, what I'm saying is that just because there is snow doesn't mean the insulation is any good.

We had 1.5 foot of snow fall in 1 day last week.
It will take a while for it to melt, but it's melting alright.
