I consider BotW 7.5/10 game (and I'm Zelda fan) and, for example, Divinity Original Sin II 9/10 game - yet, I would never say that latter is AAA game.
You would be the vast minority. To the majority of consumers who got the game, it truly deserves every award it recieved.
Kind of like how I feel I got my money's worth with The Order 1886. I enjoyed the gameplay, plot, and feel of the gunplay. I took the time to get the plat and beat it a second time on the hardest difficulty. All in all, I got about as much time as I would playing Uncharted 4 once.
However my experience alone does not measure quality, just like your experience alone does not measure quality. We have preferences sure, and that dictates how we personally value our purchases. Quality is different however.
Zelda for example, many people put in 100+ hours. I personally did 165. Horizon Zero Dawn I put in about 45 hours, got 89% of the trophies, and beat the main story. Once the credits rolled, I had no desire to play anymore. To me, BotW was a vastly more enjoyable experience. However, in terms of quality, I see them as equals and love both overall.
Back to The Order 1886. Even those who got the plat still are not guaranteed to get as much value as I did. You do not need to play the game a second time like I did. You can also get the plat on one playthrough, and if you did not, chapter selection makes it a quick task to complete. Most people who played the game played for 6-8 hours and felt the game was over priced, despite the high production value. I loved the game, but it was severely lacking in many areas.
In short, while one person can measuer their own value of what they buy, they cannot measure overall quality with their opinion alone. You need to look at mass reception and why most people feel the way they do to get a more accurate measure of quality. Other things must be taken into consideration as well, like wether or not a game is niche, but that is another topic entirely as none of the games I listed were part of a niche gener.
