Not sure where you read "everywhere" there is no support for case-difference detection (especially as you apparently just found where we state the exact opposite). We're not responsible for what other sources tell you.
There are options in all basic profile types to detect case differences (where the name is otherwise the same). These options are on Decisions-Files (bottom section) and Decisions-Folders (ditto) settings pages. Note that the options are different for SmartSync profiles (compared to Backup/Mirror)
Help > Search* > 'case' (without the quotes) > top three hits will get you Help about it, as will F1 on the various settings pages.
* if you use the Search option to 'Match similar words', it will actually be hits 1/2/4
