TCL 65C7K for 700€ or wait for other Black Friday | MINI-LED or other QLED?

Basically what the title says. Checking the market for a new TV and need some help. The TCL is one of the first Black Deals I see. It's available for 700€ in 65" or 555€ in 55" (Germany), which is at its lowest. Should I just take that one now or wait for better black Friday deals? Any experiences or observations from previous years?

The TCL C7K gets good ratings in basically any tests. Not only considering value-for-money but as well just "pure" performance. On the other side comparing example pictures on rtings (e.g. for HDR brightness: city at night) the picture does not look better than some regular QLED TVs from LG or Samsung priced similar. But my knowledge about TVs and picture quality is limited :D

Distance to TV will be around 350-400 cm, depending on final setting. Main usage will be streaming in the evening and watching Sports, what on weekends can be during the day. There are some windows behind the couch but with some good curtains I can make the room quite dark so that should not be an issue. Occasional gaming.

Was looking at a LGQNED93A as well as there was a good deal but couldn't decide before it expired. That one doesn't have HDR 10+. Is that a big issue in that category? Are these TVs capable of taking advantage of that at all?

In the past I didn't have much luck with BF deals except for a roborock last year, but I as well did not look for TVs for 8 years so I don't know if there's a big price drop to expect. Usually I only saw good deals for stuff stores can't sell regularly and want to get rid off.
