The referenced GALLOP poll only asked if the respondents believe in God/believe in a God.
Pew Research conducted a similar study and found that 90% of respondents believe in a higher power, which echos GALLOP, but only 56% believe in God as described in the Bible.
It's not clear what percentage of people believed in the Bible's God 60 years ago, but if we, for argument's sake, assume 90-100% then 56% support now is comparatively uncommon. Under those assumptions, it would be quite reasonable to think that religious culture has changed dramatically.
The key takeaway here is that communication is hard and that data is easy to twist.
