The temperature difference at 8700K is significant; should the lid be removed or left in place?

Hello overclocking Gurus,
Not a real overclocking question but your experience matters here.
I have 8700k based system with Corsair h100i v2 AIO.
The WCS is claimed to be able to handle 220W TDP.
The 8700K runs at multiplier 43/45/47/50 dependent on active core count, to keep it within the cooling budget, everything else is stock. The system is stable.
Recently I noticed a difference between indicated package temperature and the temperature reported by WCS. They run about equal with no load (~35C), but when loaded the package quickly gets to 60~80C while the WCA follows very slowly and only gets to about 40-45C in 10 minutes or so. That is a huge delta in both temperature and time.
I was thinking that it is due to weak thermal paste or a bad lid contact so I repasted it with some industrial compound (not on top of my mind) and got it reseated. It did lead to a minor improvement (less than 5C).
I was thinking the temperature sensor is erratic on the WCA so I popped the hood and got an IR thermometer pointed at the lid, reading very close to what the WCA is reporting (within 3C).
I assume that there is indeed a bad thermal transfer but it is below the lid to the die.
Now my questions are -
Is it common?
Should I get the lid off and leave it off? The die is very touchy while the WC pump is a heavy unit.
Should I leave it as is and live with it (and have CPU warranty not voided)?
Should I take the lid off, repaste and get it back on with a gasket maker?
Your opinion counts. Pls if you state “what” also state “why”.
A similar direct die cooling bracket could further reduce temperatures. This allows removing the IHS and mounting the cooler directly onto the die. Reports mention temperatures around 50-53°C at 5GHz.

Purchasing one may pose challenges, especially if your motherboard isn't compatible.
You might need to cover the IHS or use a replacement copper version.

Because there was no feedback, I am moving toward the final choice.
