Does continuously using 95-octane fuel affect the 10th-generation Accord?

Continuously using 95-octane fuel does not affect the 10th-generation Accord. Powertrain specifications of the 10th-generation Accord: The Accord is a midsize sedan under Honda. The tenth-generation model is equipped with three engines: a low-power version 1.5-liter turbocharged engine, a high-power version 1.5-liter turbocharged engine, and a 2.0-liter naturally aspirated engine. Configuration details: The 10th-generation Accord features a MacPherson strut front suspension and a multi-link independent rear suspension. The multi-link independent suspension enhances wheel-to-ground performance, which consequently improves the vehicle's handling.
I often ponder these things when driving, and there's really no big issue with using 95-octane fuel in the 10th-gen Accord. The manual states that 92-octane or higher is acceptable, with 92 being the minimum requirement. In fact, 95-octane's higher octane rating can help reduce engine knocking. However, the Accord's 1.5T engine has a compression ratio of only 10.3:1, so it doesn't actually require such high-octane fuel. Using 95 long-term is just wasting money—currently, 95 costs about 0.7-0.8 yuan more per liter than 92. If you drive 20,000 km a year, you'd spend over 2,000 yuan more on fuel. It's even less necessary for the hybrid version, as the system automatically adjusts power output. A friend of mine has been using 92-octane in his Accord for five years, and the engine is still in great condition.
