The Endless Magnificence triumph was bugged, and the fix that was implemented ticked off Hunter and Titan - the result was that the Magnificent objectives had to be completed on the Warlock to complete the triumph.
When did you complete the magnificent objectives for the white glow?
Whilst the objectives could be completed after the solstice event finished to earn the white glow, perhaps the triumphs may have been restricted to the event - I haven’t seen anything to confirm / deny this.
I finished all three sets (including the Glows) during the first week of Solstice. The Friday when the last piece of armor could be completed, specifically. The photo in that imgur album above shows my Warlock with all 5 armor pieces completed. I could post a video hovering over each item.

No need to do that, I inspected your warlock when you posted and could see the set equipped with all objectives completed.
I was trying to determine when you completed them in case the triumph was restricted to during the event.
Like you, I completed the objectives week 1 and was stuck with the bugged triumph. However, I was able to claim upon next login after the fix was implemented.
Short of me suggesting you clear your cache, which I’m not sure would help, all that can be done at this point is to wait for Bungie - for which I recommend you bump the thread to keep it active.
