I hope I'm understanding the question correctly. If I miss the point I'm very sorry! orz
Do you mean the glow around the diamond-shaped element on the right (the one that says 35% in the first picture and that has a white glow and says 82% in the second picture)?
As far as I understand, when the crystal reaches a checkpoint, it will glow while your progress to unlock your checkpoint accumulates/when the percentage number grows. It will stop glowing as soon as it becomes contested/an enemy player steps on the checkpoint and the progress growth halts. When the enemies step off the checkpoint the glow will return with the resuming progress growth. (So when enemies step on and off the glow will switch on and off as if someone was flickering a light switch.)
The first picture shows a scenario when the crystal sits on the checkpoint but no player whatsoever is standing on it so it doesn't progress/doesn't glow despite not being contested by enemies (I found a recording of mine where that exact case is happening and it looks just like in the picture).
So it's not about the winning side but purely about visualising the unlocking process. If team A has already unlocked their checkpoint (and has much more progress) but team B recaptures it, reaches their checkpoint and starts unlocking it, it will glow as shown in the picture.
As for your team and the winning team:
1. You are always blue, irrespective of whether you're Astra or Umbra.
2. Your progress number (element 2 and 3 in the OP image) will always be on the side of your name.
3. But your progress bar (element 9 and 10 in the OP image), i.e., the visual indicator of your progress will always be on the opposite side of your name.
---> If you want to have all information on your progress (visual indicator and percentage) you need to look in two different places.
So the indication of the winning side is really unintuitive. (Great design, SE!)
(Thus, since your number sits above the enemy's visual progress bar it's easy to think the number also belongs to the enemy. Because that would make sense. As they're visually grouped. But no.)
4. Whether your team name (and correspondingly your progress bar) is on the left or the right depends on the map and can even change from game to game depending on the map.
(Vulcano and Clockwork seem to switch it around randomly. I have to check wether other maps switch too. So far I have only found recordings of Palaistra where my progress bar is on the right. But yeah, you might have to readjuste anew with every game...)
I hope that explanation made somewhat sense (and if that's not what you were asking sorry again orz).
