My AWD display of my tires traction

My new Subaru I am noticing that my display with all the cars functions by
toggling the paddle of
the different functions i.e. RPMs etc.

The one I keep on the display is the one that shows all 4 tires trim
illuminated bright green while
driving.
When I begin driving one day the 2 left front and rear tires have them bright
illuminated green and
other times showing all 4 tires bright green.
Then another day or after a while parked all tires show full illumination.

I then took my car to the dealer and there was no error. This is so strange
as driving to the dealer
the 2 left tires was showing the bright green circles and when I picked up
my car after they did all
of their checks I got in my car and sure enough all 4 tires now are showing
green while driving out
of the dealer.
The car has less than 120 miles.
Does anybody have an answer please.
Thank you,
