I found something relating to price for UVO service. Apparently, we are using the "lite" version. As for the paid versions, there are tiers. Take a look...
One difference between the two is that MY2020 comes with 5 free years of UVO, while MY2021 only comes with 3 years. As for appearance, the green colour was dropped for 2021, and also for 2021 the word SOUL at the upper rear sides of the C (or D?) pillar is now filled in with a blue colour.
