AFAIK, yes... all the way up LOD-27 / QMID-29.
BTW: Considering that Area Points may be regarded as "mini-Quads", that would raise a question as to whether there are actually Quads that are LOD-37 / QMID-39 !
ex: LOD-13 + 10 = Lod-23 Quad size of Area Point
Hypothetical extrapolation:
ex: LOD-27 + 10 = Lod-37 Quad size of Area Point (0.00029296875 Meters grid interval = 0.29296875 mm between data points)
One might wonder if the FS run time rendering engine is actually able to resolve such small values !

EDITED]
CAVEAT: The extent of Meters on the ground mapped by draped aerial imagery texture pixels (aka "Texels") varies by FS Terrain Grid Quad / Area Point position on the FS 3D world spheroid / geoid.
The extent of Meters on the ground typically discussed are for a "theoretical" maximum quad "X" (Longitude) dimension of 1,023 Meters on the ground at
ex: the equator of the globe.
NOTE: The extent of Meters for Quad / Area Point span increases with AGL Altitude to the FS theoretical maximum Altitude of 100 Million Feet.
Actual
constants of measurement associated with the FS Terrain Grid Quad / Area Point extents is "
Fractional Arc Degrees" on the ground (...and in the air up to FS theoretical maximum Altitude of 100 Million Feet).

One might wonder how small terrain grid vertex intervals are rendered ...even if LODs are capped at LOD-27 ?
Welcome to Microsoft "
Molecule Simulator" ('
small world', isn't it ?)
Hope this helps a bit more !
