ENDURO tracklog colour after sw 26.00. Black OR red? (more tests were done)

You can read about the suffering regarding the same color scheme for both courses and tracklog in an archived thread of the archived Enduro forum (both were changed to red by sw 26,00), but you can also see my finding that sometimes the tracklog is black, https://forums.garmin.com/outdoor-recreation/outdoor-recreation-archive/f/enduro/336511/26-00-issue---route-has-changed-color/1708494#1708494

I made more tests since my post in that thread and I can confirm that when I use PacePro  feature, the tracklog is black. Either course navigation is enabled or not. If only course navigation is enabled, but no PacePro is used, then tracklog is red as is the course.

I can also confirm that there is no effect if one creates a Mapthemes folder on Enduro and places a .kmtf file there, It had been just a desperate bet made by me before I spotted that in some cases one can still see black tracklog after sw 26.00

Enjoy the conclusion of my test!
