Flashy 10-Ks are hugely annoying, especially in IFRS where there’s no standard. Give me tables all day every day. The lack of standardization in financial reporting already sinks enough of my time.
I hope things have improved in the years since but I doubt it. Nobody looks at the XBRL its just a regulatory box tick.
The application of XBRL doesn't really affect the design of the reports. It ebbs and flows - it feels like more designed filings are coming back with better tools that allow more designed reports.
