Currently the MCU info is very generic. Actually it shows:

more complete would be:

 - Chip Family: ESP32
 - Chip Model: ESP32-D0WDQ6-V3 (revision v3.0)
 - Number of Cores: 2
 - Max CPU Frequency: 240MHz
 - Has Bluetooth: YES
 - Has Embedded Flash: NO
 - Has Factory-Calibrated ADC: YES
 - MAC Address: 08:B6:1F:80:9D:94

N.B. The "MAC Address" can be a bit tricky for modules which do not have WiFi, like the ESP32-H2/P4 (and others which are not yet available)

For the P4, there is a built-in MAC address, but the WiFi is done via some external ESP. Typically this is an ESP32-C6 running ESP-Hosted-MCU firmware (or not... as there are boards out there which have this module not flashed)
The built-in MAC for the P4 is used for RMII Ethernet, but this isn't the first entry.
