In just 8 days, that hexagonal piece of equipment installed on the InSight lander changed its general appearance from dull to shiny copper (see image 1 and 2). How is it possible?

Explanation, That question with answers, that were also suggested as answers for my question, does not explain the radical change in appearance from dull to shiny cooper. I see there a discussion about an optical illusion unrelated to my question.
