"Boundary reinforcement is not related to room size, it’s depending on distance to the boundary only"

That's what I said, but increase the room size without changing the listening triangle and the speakers are going to be further away from at least one wall so boundary reinforcement will decrease. Maintain the distance to boundaries and listening distance increases. You can't maintain both listening distance and boundary reinforcement at the same time without changing the angle the speakers subtend at the listening position and that introduces another variable.

But, apart from boundary reinforcement, there is another factor. If you maintain the listening triangle in the larger room, and increase the distance to one or more boundaries, you also increase the reflection path from those boundaries and that is going to reduce the level of the reflected sound eventually reaching you, and that in turn is also likely to have an effect on your perception of actual listening level.

Of course, how much of an effect you get from either of those factors depends on the size of the increase in speaker to boundary distance. It may or may not be a factor depending on which room dimensions increase and how the listening triangle is placed in the room.
