“Protestant” service is an awful broad category.
Which is one reason i said it was a contrived Catholic polemic=showing effects of planning or manipulation. All that is needed is one Prot service that hardly reads from the Bible, of which there are plenty, or those who preach for 45 minutes or more on just a few texts, which is quite common, though they may sing also many over the 45 minutes of worship, plus what they read in midweek Bible studies.
The real issue is who reads and hears more of the Bible, those for whom Scripture is supreme or those for whom a church is supreme.
68% of Evangelical Christians attend a regular Bible Study or participate in some other small-group activity. 47% of other Protestants take part in small groups related to their faith, along with 24% of Catholics. ^
