I measured the distance from the TV to the sofa. The length of the living room is around 13 to 14 feet. The distance to the farthest sofa would be 12 to 13 feet. There is a large sofa to the left and chairs to the right of the TV. Their distance would be around 8 feet or less. The minimum viewing distance is easily covered for the 55-inch and 65-inch TVs from the chart.
I found another chart for comparison. The view distances are shown below:
40-inch, Full HD will be around 5 to 5.5 feet (My current Sony TV)
55-inch, 4K will be 3.5 to 4 feet
65-inch, 4K will be 4 to 4.5 feet
The above information might benefit the 65-inch TV more.
Then, I found another chart for the optimum distance. I posted the link to the chart below:

It looks like the 55-inch would be better than the 65-inch TV at a distance of 12 to 13 feet.
The breadth of the wall to place the TV in my living room is 60 inches. The length of a 65-inch TV would be 58 inches. This would make it difficult to fit the TV onto the wall. On the other hand, the 55-inch TV would be 48 inches. If there is a 60-inch TV available, that would be the best size for my wall.
With the above statistics, I think the decision for a 55-inch or a 65-inch TV can be answered.
The Frame TV looks innovative and beautiful. I would buy it if the 55-inch variant came below Rs. 70,000.
For my current TV, I think the following would be noticeable upgrades:
Sony Bravia X74L improves 4K resolution, size, LED-backlit, Smart TV features
Samsung the Frame (2022) enhances sound (40w), refresh rate (100Hz), and brighter colours (qLED) in addition to the above
