It surely seems improbable that most of people in the 1920s were dreaming black and white while today 80% dream in color.
If this study occurred in the US then it isn’t so improbable. In the 1920s the primary form of entertainment were black and white movies. This might have had enough influence that many of the people who would have had dreams in color had substantial parts of those dreams in “color” but the only relevant colors were black and white. (This notion is partially inspired by my own dreams- I dream in color, but occasionally cartoon characters show up, and when they do, they look like they would in the cartoon even as they interact with normal people, or something sort of like that. So it isn’t implausible to me that something similar could happen with black and white characters.)
That did occur to me, but I doubt the real influence of movies can be that big as to make all dreams of 80% of people black and white. What seems more likely to me is that the colour of dreams (or actually the whole visual quality of dreams) is hard to remember, a person familiar with b/w movies would be likely to assume that dreams are similar to movies, and therefore report that they were black and white. But the two theories seem very hard to distinguish empirically.

You could have people watch only black and white movies for a while and see if they were more likely to report dreams being in black and white. This would work since people today know that entertainment isn’t in black and white. Alternatively, one could take black and white media and project it in some strange color scheme (like say orange and blue) and see if people started dreaming in that.
I believe the primary form of entertainment for the last million years has had plenty of color.
How is that relevant? If the entertainment at any point (especially when there’s lots of entertainment) impacts what dreams are like then what entertainment our ancestors have had won’t be relevant.

That would distinguish the hypotheses
Watching lots of black and white movies directly causes dreams to lose colour.
Knowing that all movies are black and white corrupts one’s memories about one’s dreams.
But it will not decide between
