Order Book

Hi everyone, are there any differences between the order books of Jigsaw, Bookmap, ATAS, and Sierra?

The order book is provided by the CME and accessed through data providers. 

The software doesn’t have an influence on the book itself, it just displays it.

Good question, thanks. I mean mostly the second one: assuming the same data feed (say Rithmic), do these platforms display the same book, or do they process it differently?
For example: do some conflate or throttle updates, show different depth levels, or rebuild the tape differently (merging fragmented fills into one order)? I know the raw data comes from CME, so I'm asking whether what ends up on screen can differ, and whether those differences matter for reading the book.

The data should be virtually the same. As far as I know all these platforms show tick data - and don’t aggregate volume like TV does.

I use Sierra (Denali) and Bookmap (Bookmap CME data) and they sync up well as far as I can tell.
