Rest assured, the IR will go away, but it can take months and months.
I have a 65VT30 and a 65ZT60 .. the VT30 had a CNN logo for 9 months of 16:9 viewing until it finally went away, and I developed it after watching a well broken in panel for 12 hours on CNN ... Also those pixel flippers and screen wipes do nothing -- at least they did nothing for my sets -- I ran them 24/7 for days and days -- no change at all. God bless people that swear by them, they did NOTHING for me.
After 4 hours of cnn viewing on the ZT, IR developed for the logo.. and it took 2 days to completely go away.
The 9 months on the VT30 was very frustrating, but once it went away as everyone told me it would (and I didn't believe them) -- I now don't care, I know that IR just goes away after some time, and you'll have to deal with it while it is still present
Definitely have to be careful what you watch on these sets
