Surface Pro 4 tilt function on sp5 screen? [PRO4]

[siggi]

The Microsoft replaced the flickering screen on my SP4 to the screen of SP5, can the sp4 with sp5 screen now support tilt function? I think the hardware is the same.

I also tried to install sp5 drivers but failed to extract the WinTab driver

The compatibility chart for SP5 indicates ...
"Surface Pen tilt functionality is available. May require updated firmware."

I'd suspect there is no firmware update for the SP4 that would enable the functionality but that's just my guess. Also, I believe the pen itself would have to support it.
