I disagree strongly. Dimensions are purely physical, and as such, physical/material space is encompassed in the first three. Time is usually (but not always) counted as the fourth dimension (and is also physical). The spirit realm, not being physical, is not one of the dimensions.
The creation is not anything "manifesting God"; it is the result of God's creative words. Jesus' incarnation is God's appearance within creation as a physical, mortal being.
While the Flatland analogy is useful for illustrating both higher dimensions and the spiritual realm, it fails (as all analogies do) to represent wholly and accurately the nature of the Trinity.
Here we agree: while some measure of understanding is necessary, belief where understanding fails is an appropriate response to God.

If Jesus' incarnation is God's appearance within creation as a physical, mortal being, then there is no good reason to think creation is not God's appearance as physical, material things.
While the Flatland analogy is useful for illustrating both higher dimensions and the spiritual realm, it fails (as all analogies do) to represent wholly and accurately the nature of the Trinity, which is why "we may have trouble understanding the concept of Trinity fully from a human point of view".
IOW, we agree while some measure of understanding is necessary, belief where fallible understanding fails is an appropriate response to God.
