I didn't check, but I think I saw in the controller specs of the D67 that it activates the BUSY line during hibernate. So, if you have any load on the BUSY line, this could explain the current draw.
Do you only hibernate the display, or do you use deep sleep of the ESP32?
The ESP32 has internal pull-ups or pull-downs on the "strapping pins", for boot mode selection.
