I've had this TV now since I created this thread. Some of the issues you guys are posting about e.g. dropouts etc. sound like sub par HDMI cables. I thought I had a HDMI 2.1 cable before, and had these dropout issues. Since changing cables, no major issues.
Make sure to go for Ultra High Speed HDMI Certified Cables. This should clear up most of the issues.

As for picture quality, with a little tweaking, I have no issues at all. It pops better than my QE65Q9FN. Brighter when it needs to be, local dimming is far superior when it needs to be with significantly less haloing.
My main use is PC gaming. I use it as an oversized 120hz 4K monitor. Enabling game mode really screws up picture quality requiring a lot of colour adjustment to get it right again.
Using it to watch UHD Blu Rays, HDR is awesome.
Biggest issue is eARC for me. It is an absolute mess. Reading other TV brand threads, it's not Samsung specific, its the eARC standard that seems to be crap.
If I enable ATMOS on PC, XBOX Series X or anything else apart from inbuilt apps (Netflix, Amazon Video etc.), there is a massive audio delay that just cannot be resolved.
If you have an ATMOS compatible eARC sound bar / AV Receiver, and having issues getting Netflix to work with ATMOS, there is a workaround I figured out.
Switch the TV off fully via plug switch for a few secs and then on again(This ensures Netflix will not quick launch)
Make sure your Sound bar / AV Receiver is on and all the eARC functions on TV and sound device is on.
On the remote, select Home > Apps >Settings (Cog top right corner) > Scroll to Netflix and then reinstall it.
Launch Netflix, and ATMOS should now work with no lip sync issues. Lost In Space is a good test for this.
For the guys thinking about buying this TV, my advice is that if it is going to be used mainly as a gaming display where there are plenty of static images (HUD, mini-map etc.), go for it. If not, stick to OLED.
Gaming is the only reason I am sticking to LCD or else i would have been on the OLED choo choo train long time ago. Screen burn on a £2K+ TV not worth it! Would ruin my immersion.
