In none of the services was there a sense of the Holy, or a tangible focus for the worshippers.
I wonder if one was to video tape the expressions of the faithful of the parishes I regularly attend on Sundays (I bounce between an OCA and UOC parish) if you would think we were filled with a "sense of the Holy."
Some probably would look bored. Others might be distracted by trying to keep the "little ones" quiet and settled during the Liturgy. You probably would see a few that had fallen asleep during the sermon. I'm sure a few might be able to put together a pious expression or two, but the last time I checked, God judged our hearts, not necessarily our outward expressions as to the depths of our devotion.
I have attended services in person of other denominations within Christianity, and I have also watched services on TV. (I have enjoyed watching Mass and the saying of the Rosary on EWTN on more than one occasion) and the I think it is very unfair to watch one service and to make a judgment as to the level of reverence or regard for God based on that one service.
In reality, most other Christian worship services are pretty watered down when compared to the Divine Liturgy. We Orthodox like pomp and circumstance. Our vestments are more decorated than most, our churches are fancier than most, and we do have a fondness for our "smells and bells."
I say this, not as a criticism for us Orthodox, but to point out that it really is an unfair comparison to put a Lutheran service next to the Divine Liturgy and hope that the Lutheran service will pass muster. Martin Luther intentionally watered things down. That was part of his "reformation." So naturally, Lutheran Churches are not going to be as highly decorated, etc., etc., as Orthodox parishes.
Like you, I am biased and love our Orthodox services and all of the beauty that comes with our Churches. However, I would never doubt the sincerity of those in the pews of another church.
The person you saw sitting in the pew on TV may have been struggling with their faith in God this year, and chose that service to try to reconnect in some way with the Almighty. Something drew them to Church that day. And the fact of the matter is that they were in Church, and not out at some strip club or doing something awful. So, give credit where credit was due. They came to celebrate Christ's Nativity in their own way, and that's what they did.
May God bless them for it.
