E.g. 20 of first 24 games on the road, including the 14-game road trip (not going to help road record.) And on the flip side, means they were at home a significant amount of time after that relative to normal/their opponents. Comfort improves home record, getting to travel significantly less for the last roughly 70% of the season is going to help home record.
Plus, of course, visiting opponents own comfort, not having NHL standard locker rooms/facilities/etc which are a byproduct of but not necessary because of a "small arena" (capacity wise.) Not sure I'd draw the conclusion that small capacity arena equaled significant home ice advantage.
Fully agree with your first point the higher home/road ratio later in the season could have bumped the home winning % higher. Would be an interesting study for the stat geeks.
Don‘t agree with the second point on visiting team comfort. The first 4 visiting teams had to deal with the temporary setup. The other 37 visiting teams used the newly finished NHL caliber locker rooms and facilities.
