Bravia 9 would be my ideal pick but It does not come in a 55 in size so now I am thinking about the Bravia 7 . Is that the best 55in mini led tv or is there something else?

I am running into multiple limitations hunting for a new tv to replace an old QLED TCL C725.

1. Very bright room which has large windows on the opposite wall of my TV placement, during afternoon the sun light directly hits the TV screen.

2. Limited by size: 55 inches maximum. The backwall width is only 1330mm - 133cm with other room doors on both edges of the wall. So technically can't have a tv overflowing the backwall boundaries.

I just cannot seem to find any budget high brightness, high zone count TV's at 55 inches. All the good mini leds I have come across TCL C8K, Hisense U8 Series start at 65 inches.

OLEDs like G5 and S95F are out of question: High Prices and low overall full window brightness: 250 - 350 nits. (Also heard that direct sunlight really hurts the viewing experience).

The only options I see available is TCL C7K but it's got really bad reviews on rtings (QM7k) or the U7QAU with no reviews.

Bravia 7 is way out of budget (2000$ more) and spec wise seems similar to C7K, Bravia 9 has no 55 inch version.

Is TCL C7K the only real option at this size limit? or are there any new models expected with similar specs like TCL C8K at 55 inches?
