In regard to the display: Yes, those marks come from the keys pressing against the display. Be careful how much you fill in your backpack with the MBP. My display looks very bad around the space bar (that is the 2018 "improved display"). Noticed that way too late. An Apple Genius recommended me to always have a microfiber cloth between display and keyboard when traveling. Not on a $3000 device thanks.
Heating/fan issues, double typing keys, too many "-gates" to count. I never had so much buyers regret.
