Google Gemini helped in my devision:
"While they may look similar on the shelf at Costco, the TCL 85" QM6K and the Costco TCL 85Q77K are different TVs with significantly different backlight technologies.
The Main Difference: Mini-LED
TCL 85" QM6K: This is a Mini-LED TV. It uses thousands of tiny LEDs to provide much better brightness control and deeper blacks.
TCL 85Q77K: This is a standard QLED (Direct LED) TV. It does not have Mini-LED technology. It uses larger, traditional LEDs for its backlight.
TCL 85" QM6K (The Higher-End Model)
The QM6K is part of TCL's 2024/2025 "M" (Mini-LED) class. It is designed for a more premium HDR experience.
Backlight: QD-Mini LED with Full Array Local Dimming (up to 500+ zones).
Contrast: Because it uses Mini-LEDs, it can get much darker in black areas of the screen without "bleeding" light into bright areas.
Brightness: Typically reaches higher peak brightness, making it better for bright rooms (like those in Arizona).
Gaming: Supports up to a 144Hz VRR refresh rate.
TCL 85Q77K (The Costco Value Model)
The Q77K is often cited as a Costco-specific variant that effectively replaces the older Q7 or Q6 models. It is a very good "mid-range" TV but lacks the precision of the QM6K.
Backlight: Standard Direct LED (Full Array). While it has local dimming, the LEDs are much larger than Mini-LEDs, which can lead to some "blooming" (halos around bright objects).
Performance: Reviewers often note that while it looks great for the price, its black levels aren't as "inky" as the QM6K.
Value: It is almost always cheaper than the QM6K and usually comes with Costco's extended 5-year warranty bundle.
Summary: Which should you choose?
If you want the best possible picture quality for movies and high-end gaming, the QM6K is the clear winner because of the Mini-LED technology. If you are looking for the best "bang for your buck" on a massive 85-inch screen and aren't as concerned about perfect black levels, the Q77K is a solid value choice."

Thanks !
According to Costco reps and store signage the 3 years of Allstate warranty starts after the 2 year manufacturer warranty.
5.7 rating is a red flag.
But if you're on a budget, you wont find 85" tv at this price except on BF. I personally won't host superbowl party with this TV.
