This is more an API question than a filesystem one.
Windows NT using NTFS is casepreserving-caseinsensitive when programs
use Win32 API, and case-preserving-casesentivie when programs use POSIX
API.
Also, FAT is case-preserving, but as the DOS API always capitalize the
filenames, it seems not to users (it also support spaces, and NOT im not
saying VFAT or LFN, but original FAT).
