Stating conclusively plants do something is less accurate than stating the impacts are inconclusive.

Once you open the window or door you reduce the impact of the plant as you vented. It is the exteme concentration and no air flow that can show some impact.

Natural sunlight is so different all the time and location specific. A full spectrum light on 24 hours a day with a set temp will have more heat units than the same plant set in direct to indirect light for the limited day length. The individual care of the plant itself and the soil health would result in dramatic differences.

Plants are fantastic but even a lot of plants are not going to be as impactful as this video makes them out to be.
