It's gotten better.
 

So the TV has gotten better on it's own over the past few weeks. Notice here when I decided to game, I can't spot any blooming whatsoever. So now not only color has improved, picture stability has too.

Sorry for lack of editing on this video. I was tired and so this is actually a raw clip right from the cameras memory card.

That's awesome. I have been watching your vids of this TV.

Side note: In 2002 I had gotten off the side of the road a 1985 Samsung TV like yours but with electronic tuning. Though I don't think it was cable ready. Still worked and everything. They just cut the power cord off of it.
