[UUF] Clarify case sensitivity

### Type of issue

Missing information

### Description

"When this method returns, if the conversion succeeded, contains true if value is equal to TrueString" Would appreciate if the documentation clarified whether "equal" was referring to case-sensitive or non-case-sensitive equality. I initially assumed case-sensitive, but from my own testing, it seems to be non-case-sensitive.
