STM32L4 ART Accelerator Data cache

I understand the ART accelerator is designed to improve performance at high speeds (when FLASH wait states are nonzero)

But does the ART accelerator (in particular the Data cache) give any benefit if wait states are already zero, for example when the CPU runs at 4 MHz?

That is, if the code is straight-line with no looping or branching, does the Data cache help.

If it does, is there any document that gives more detailed information how to make best use of this feature (for optimising assembly language routines).

thanks.
