WD Blue SN550 firmware 211210WD is old revision I guess?

I recently heard, that new sn550 revision uses new QLC memory type and new firmware is 233010WD. So I guess my SSD with 211210WD firmware is older one with TLC memory? I bought it in this July

Firmware 211210WD would indicate the older non-crippled model of the SSD. I have the same firmware in mine (purchased last year).
