MiniLED is just what’s lighting up a panel, The panel type is what matters. For example You could have a mini-LED lighting an IPS panel that has poorer contrast but better viewing angles or a Mini-led VA panel that has better blacks but poorer viewing angles. It looks like Apple went for better blacks.
Apple used to advertise the MacBook Pro as IPS displays, they no longer do that on the MBP 14,16 meaning they've moved to a different panel type. Expect the newer models to feature VA panel characteristics
instead of IPS. From the comparison page on Apple's site between 13.3 and 14.2, as well as 16 and 16.2 MBP:

Some information about panel types.
Modern monitors either contain an OLED panel or an LED-backlit LCD panel, with the latter being commonly known as an LED display. Both OLEDs and LEDs have different panel types, each with their own strengths and weaknesses.
