Not to diminish your valuable insight, but if they were simulating a sunrise, I doubt they had these at full throttle. My guess is they used old school lightning panels because of the orangey filament glow at lower wattages. WDYT?
Day for night shooting is a similar idea - by changing color balance and adding more light to emulate the moon - it's possible to give the impression of darkness.
An yes, they are probably going for an orange glow inside.
The mentioned foam is on the inside of the cabin liner. The interior walls that line the actual pressure hull. The foam seals role is probably noise and vibration reduction, not pressurization.
