Many opinions on logic level voltages.
My understanding is that these WS2815 have an internal voltage regulator VDD 12V down to VCC 5V for the logic circuit. Unfortunately the cited datasheet is not very clear about this and does not specify the target value of VCC. Also later the the abbreviation VDD and VCC are possibly exchanged in the "Electrical Characteristics (TA=-20～+70℃, VDD=4.5～5.5V". The data input voltage levels should be kept in the VCC range.
