Does Espressif burns unique MAC address in eFuse for every ESP32 device?

[ajaymm58]

Seeking confirmation on the following items: (else otherwise)
1. Each ESP32 device* has WIFI_MAC_Address (56-bits=48-bit MAC Address + 8-bit CRC) uniquely programmed at factory.
(*not the module, the IC itself)
2. For MAC address in eFuse "24:0A:C4:HH:MM:LL" total of four MAC addresses ":LL", ":LL+1", ":LL+2", ":LL+3" are assigned when
FOUR_MAC_ADDRESS_FROM_EFUSE config parameter is selected and function
esp_err_t esp_read_mac(uint8_t* mac, esp_mac_type_t type)
is invoked for each of the type value 0:STA, 1:SOFT_AP, 2:BT, and 3:ETH
